This article has been archived, and is no longer maintained.

You must set up WANJet appliances in pairs, with one appliance on each side of the WAN link. You can perform the configuration steps for both appliances either on each physical appliance, or from a single computer by logging on to the Configuration utility remotely.
You can alternatively deploy and manage multiple WANJet appliances from the Enterprise Manager, a centralized management solution. To use it, you need to have purchased and set up Enterprise Manager, which is a separate product from the WANJet appliance.
WANJet appliances work in pairs to optimize the traffic that flows between them. A pair of WANJet appliances consists of a local WANJet appliance and a remote WANJet appliance, one on either side of a WAN link. A typical configuration might include one WANJet appliance in a data center where company servers reside, and a second WANJet appliance on the other side of the WAN in an office where employees work.
Figure 3.1 shows two WANJet appliances that are deployed in a point-to-point configuration.
WANJet2 is in a remote office and connects to the remote end of the private IP WAN link with an IP address such as 10.2.0.1.
You use the Liquid Crystal Display (LCD) panel, a computer connected to the WANJet appliances serial port, or a secure shell (SSH) to configure the Management port IP address, netmask, and gateway, or the WANJet IP (bridge IP) address, netmask, and gateway.
Basic installation is covered in the Quick Start Card that ships in the box with the WANJet appliance. If you have already performed the basic configuration steps on the Quick Start Card, you do not need to repeat them.
After you complete the initial hardware configuration, you can log on to the WANJet appliance using either the Management IP address or the WANJet IP (bridge IP) address. If you configured the Management port, you should use the Management port IP address to log on.
You can then set up the WANJet appliance using the browser-based interface, called the Configuration utility. If using out-of-band management and the Management port, you can access the Configuration utility from any computer that is connected to the management network, and can run a web browser. If using the WANJet IP (bridge IP) address to log on, you can use any computer that can access the WANJet appliance and run a web browser.
The rest of this chapter describes how to log on to the system using the Configuration utility and perform the basic configuration required for the WANJet appliance to start processing traffic.
After you finish installing the WANJet appliance, you can log on and use the Configuration utility to administer the appliance and perform additional configuration. Refer to Chapter 4, Using the Configuration Utility, for a description of the web-based interface.
You need to log on to the Configuration utility of each WANJet appliance to fully configure it (unless you are using Enterprise Manager for administration).
For example, if the Management IP address of the appliance is 192.168.168.102, type https://192.168.168.102 in the web browser. If you do not have a management network, use the WANJet IP (bridge IP) address instead.
The Authentication Required screen opens where you can log on.
2.
Type the user name and password.
The default user name is admin, and the default password is admin (unless it was changed by a local administrator).
3.
Click OK.
The first time you log on, the Setup Utility Welcome screen opens.
The first time you log on to the WANJet appliance, the Setup utility opens on the screen. This is where you need to configure basic settings.
1.
When you log on to the system for the first time, a message tells you that you must complete the Setup utility. Click Next.
The Setup Utility License screen opens.
2.
To begin the licensing process, click Activate.
Follow the onscreen prompts to license the system. For additional details, see Activating the license.
3.
Click Next.
The Setup Utility Platform screen opens. This is where you specify base configuration information for managing the system.
If you configured the Management IP address, netmask, and gateway from the LCD, the Management Port settings are already filled in with the values you specified. Skip to the next step.
If you configured only the WANJet IP (bridge IP) address, the Management Port settings are blank. However, you must still type an IP address and netmask (use fictitious ones) to proceed with the setup:
IP Address: Specify a fictitious IP address for the Management port, for example, 1.1.1.1.
Network Mask: Specify a fictitious netmask for the Management port, for example, 255.255.255.255.
Management Route: Leave this setting blank.
Note: If you assign a fictitious IP address and netmask to the Management port, be certain that these addresses do not conflict with others in your network topology.
5.
For the Host Name setting, type a fully qualified domain name for the WANJet appliance. An example of a host name is mywanjet.wanopt.net.
6.
For the Host IP Address setting, select one of the following settings:
Use Management Port IP Address to assign the Management port IP address to the host name. This is the default value, and is the correct value to use if you have configured the Management port.
Custom Host IP Address to assign a different IP address to the host name. A box opens where you can type the IP address. If you are not using the Management port, select this option and type the WANJet appliance IP address.
7.
In the User Administration section, for the Root Account and Admin Account, type and confirm the passwords. By default, the root password is default, and the admin password is admin. We recommend that you change them.
8.
Click Next.
The Local WANJet appliance screen opens.
Note: If you configured the Bridge IP address, netmask, and WAN gateway from the LCD, values you specified are shown on the screen.
9.
In the WANJet Alias box, type a name for the WANJet appliance.
10.
If you have not already configured the WANJet IP, WANJet Netmask, and WAN Gateway, you must configure them now. These values are required even if you configure the Management port.
11.
In the LAN Router box, type the IP address of the LAN router (if your network configuration includes one) that resides between the WANJet appliance and the LAN. The LAN router must be in the same subnet as the WANJet appliance. This setting is optional.
12.
Click Save.
The WANJet appliance saves the settings, closes the Setup utility, and opens the Welcome screen. You can now continue with basic configuration.
13.
In the navigation pane, expand WAN Optimization and click Operational Mode.
14.
Make sure that Mode is set to Active.
If your local area network has multiple subnets connected through a router, you need to configure the local router IP address and add the local subnets that you want to optimize on the WANJet appliance. If your network configuration uses a LAN router, you need to add subnets behind that router for which you want the WANJet appliance to optimize traffic.
Once the WAN link between the WANJet appliance pair is up, subnet specifications are automatically exchanged between the appliances. So, for example, the local subnets you configure on WANJet1 appear as remote subnets on WANJet2, and local subnets on WANJet2 appear as remote subnets on WANJet1. You can view a list of remote subnets on the Remote WANJets screen.
Before performing the following steps, verify whether you need to configure the WANJet appliance so that it can optimize traffic from additional subnets, and determine whether you are using a LAN router between the WANJet appliance and the LAN.
2.
In the navigation pane, expand WAN Optimization and click Local WANJet.
The Local WANJet screen opens.
3.
Click Local Subnets.
The Local Subnets screen opens. By default, Include WANJet Subnet is selected, and the local subnet in which the WANJet appliance resides automatically appears in the list of local subnets.
4.
Click the Add button.
The Add Local Subnet screen opens in a separate browser window.
5.
In the Local Subnet box, type the IP address for the subnet.
You can use the shorthand address format of, xxx.xxx.xxx.xxx/nn, to provide both the subnet address and the subnet mask. For example:
Where /24 means that the first 24 bits of the address must match the local subnet address and the address of any host in the subnet is defined by the last 8 bits of the address. For example, 172.16.2.6 is a valid address for the subnet defined in this configuration example.
6.
In the Netmask box, type the subnet mask. For example:
Note: If you entered the subnet address in the /nn format, as described in the previous step, the system automatically populates the corresponding subnet mask box.
7.
In the Alias box, type a string to serve as a name for the subnet.
For example:
8.
For Operational Status, click the Enabled button.
9.
Click OK.
The Local Subnets screen opens with the new subnet in the list of local subnets.
10.
Click the Save button.
After you finish adding subnets to the first WANJet appliance, define the second appliance as a remote WANJet appliance of the first one.
1.
In the navigation pane, expand WAN Optimization and click Remote WANJets.

a)
Type the bandwidth of the link (32622). The default is 622.
b)
Select the unit of measure: kbps (kilobits per second) or mbps (megabits per second). The default is mbps.
7.
In the RTT box, type the value for the average round trip time for the WAN link. You determine the RTT by using the ping utility to send a request to a device on the other side of the WAN link and reviewing the command output. The default RTT is 50 milliseconds.
8.
In the WANJet Alias box, type the name of the remote WANJet appliance. For example:
9.
Leave the settings as they are for WANJet Port (the default value is 3701) and MTU (this setting is only available if you specified a LAN Router).
10.
In the Shared Key box, type the shared key. The only requirement for the key is that it matches the key added for its partner in the pair. For this example, you must use the same key when adding WANJet1 as a remote WANJet appliance on WANJet2.
11.
Click OK.
The popup screen closes.
12.
On the Remote WANJet screen, click the Save button.
The new remote WANJet appliance appears in the Remote WANJet appliance list.
After you finish configuring the first WANJet appliance, you can configure the second WANJet appliance in the pair. The second WANJet appliance must already be installed as described in the Quick Start Card included in the shipping box.
If you have more than two WANJet appliances to configure, continue to set them up in the same way. For point-to-multipoint configuration, set up one WANJet appliance as the hub and the other WANJet appliances as remote appliances on the hub. On each of the remote appliances, set up the hub only as a remote appliance. For a mesh configuration, on each appliance, set up all other WANJet appliances as remote appliances.
Log on to the second WANJet appliance as described in Logging on to the system. The first time you log on, you must run the Setup utility.
If you have added subnets on WANJet1, you must do the same for WANJet2, unless WANJet2 is on a simpler local area network. Refer to Configuring multiple subnets, for instructions.
After you finish adding subnets to the second WANJet appliance, define the first appliance as a remote WANJet appliance on the second WANJet appliance.

8.
In the Shared Key box, type the shared key.
The only requirement for the key is that it matches the key you use when adding this WANJet appliance as a remote WANJet appliance on the remote appliance. For this example, you must use the same key when adding WANJet2 as a remote WANJet appliance to WANJet1.
9.
Leave the settings as they are for WANJet Type, WANJet Port, and MTU (this setting is available only if you specified a LAN Router).
10.
Click OK.
The popup screen closes. The new remote WANJet appliance appears in the Remote WANJet appliance list.
When the WAN link is established between the pair of WANJet appliances, the two systems automatically exchange subnet specifications. For example, the local subnets that you specify for WANJetA become remote subnets for WANJetA in WANJetBs Remote WANJet appliance configuration information.
You can test the connectivity between the local and remote WANJet appliances by viewing the following details on each:
1.
Above the navigation pane, check the dashboard to see whether the WANJet Links and Operational Mode are Active.
If the dashboard shows both the links and mode as Active and the indicators are green, the two appliances are up and running, and they are communicating.
2.
If the WANJet Links or Operational Mode are not Active, in the navigation pane, expand WAN Optimization and click Operational Mode.
3.
Make sure that Mode is set to Active.
In the navigation pane, expand WAN Optimization and click Remote WANJets.
The Remote WANJets screen opens and displays a list of remote WANJet appliances. A green light displays in the Status column for remote WANJet appliances that are enabled and connected.
1.
In the navigation pane, expand WAN Optimization and click Diagnostics.
The Diagnostics screen opens.
2.
From the Connectivity menu, choose Remote WANJets.
The Diagnose Remote WANJet report opens.
3.
Review details about each remote WANJet appliance, including its IP address, whether a ping from the local WANJet appliance was successful, and whether the connection between the two appliances is operational.
The initial configuration steps described in this chapter are only the minimal steps you need to take to establish a WAN link between two WANJet appliances and start optimizing traffic between the two.
When you have completed the initial configuration steps, we recommend that you perform additional administrative tasks, such as the following:
Refer to the other chapters in this document for additional configuration that you can do to fine-tune the WANJet appliance for your environment. For example, refer to Configuring redundant peers, if you want to deploy WANJet appliances in redundant pairs. In general, Chapter 5, Managing WANJet Appliances, describes how to change the configuration that you completed while running the Setup utility. Chapter 8, Configuring Advanced Settings, explains some more advanced configuration tasks.
You typically activate the license associated with your WANJet appliance during the setup process. The WANJet appliance cannot optimize traffic until the license is activated. If you have run the Setup utility, you may have already activated the license. (To see if the license is already activated, in the navigation pane, expand System, then click License to see the license status.) This section provides additional details on the license activation process if you need them.
You can activate the license automatically or by using the manual procedure. You only need to activate the license once. If you update the WANJet appliance in the future, the license information is retained.
The license purchased for the WANJet appliance is associated with the bandwidth of the WAN link. To change the bandwidth of that link, you need to contact F5 to obtain a new license, then activate it.
Automatic activation is the easiest method because the WANJet appliance directly connects to the F5 license server and handles the activation. Automatic is the default setting if the system locates a route to the license server. However, in certain cases, you may need to manually activate the license. For example, follow the manual procedure if the WANJet appliance does not have a direct connection to the Internet, or if it resides behind a firewall that does not allow for a direct Internet connection. If the system does not find a route to the license server, only the Manual setting is available.
To manually activate the license, you need an administrative workstation with a connection to the WANJet appliance and the Internet.
In the navigation pane, expand System, click License, then click Activate or Re-activate.
2.
For Base Registration Key, you should see your registration key (filled in at the factory).
3.
Next to Activation Method, click Automatic.
4.
From the Outbound Interface list, your selection depends on your configuration:
Select mgmt if you configured the Management Port.
Select wan if you are using the WANJet IP address to log on to the system.
5.
Click Next.
The EULA (End User License Agreement) screen opens.
6.
Read the EULA, and then click Accept if you agree to the conditions.
The WANJet appliance automatically activates the license.
Note: If automatic license activation is not available, you can use manual activation instead, described in the next section.
In the navigation pane, expand System, click License, then click Activate or Re-activate.
2.
For Base Registration Key, you should see your registration key (filled in at the factory).
3.
Next to Activation Method, click Manual.
4.
From the Outbound Interface list, your selection depends on your configuration:
Select mgmt if you configured the Management Port.
Select wan if you are using the WANJet IP address to log on to the system.
5.
Click Next.
The Manual Activation screen opens.
7.
Click the link, Click here to access F5 Licensing Server, located below the dossier.
In a separate browser, the Activate F5 License screen opens.
8.
On the Activate F5 License screen, paste the dossier that you copied, and click Next.
The Activate F5 Product displays, still in a separate browser.
9.
Read the license, then select the option, I have read and agree to the terms of this license, and click Next.
The license information is displayed on the Activate F5 Product screen.
10.
Select the entire license (Ctrl + A, Ctrl + C), and paste it into the Manual Activation screen after Step 3: License.
11.
Click Next.
The WANJet appliance activates the license.
In the navigation pane, expand System, click License. The License Properties screen opens and displays the license type, the date the WANJet appliance was licensed, the date the license expires, and active and optional modules.
One of the first steps we recommend for troubleshooting the WANJet appliance is to create a system snapshot immediately. It provides detailed information about the WANJet appliance, including:
Refer to Creating system snapshots, for information on taking a system snapshot. You can provide the system snapshot to the F5 Networks Technical Support team to help resolve technical issues.
Some common problems are listed in Table 3.1. If you are experiencing an issue that is not included in the following table, contact http://www.f5.com/customer_support/ for assistance.
I can ping the WANJet appliance, but I cannot ping the WAN gateway.
Make sure that you connected the gateway router to the WANJet appliances WAN port, using the supplied crossover cable.
I cannot see that the WANJet appliance is optimizing traffic, or the optimization is extremely low.
Review your configuration of local subnets at both appliances. You might have heavy traffic on a subnet that is not included in the WANJet appliances configuration. You must include all subnets for which traffic should be optimized.
My browser connection times out when I attempt to log on to the WANJet appliance.
Check to see that you are accessing the correct URL for the Configuration utility. If you enter just http:// followed by the IP address, it will not work. You must use the secure HTTPS protocol. For example: https://123.123.123.123/
When I attempt to access the Configuration utility, I get a Page Not Found error.
If you are certain that you entered the URL correctly and the WANJet appliance appears to be running, it may indicate that the computer from which you are running your web browser does not have access to the Configuration utility. Although the default setting grants access to all machines, that setting can be changed to limit access based on IP address.
Log on from a computer that is within the network. After that, use the Configuration utility to change the access settings. For instructions, see Configuring local user accounts.
