When you initially configure the local WANJet appliance (as described in Chapter 3, Beginning to Configure WANJet Appliances), you specify the network settings for the WANJet appliance, such as IP address, ports, subnets, redundant peers, and connected remote WANJet appliances.
From the Local WANJet appliance screen, you can edit the network information, such as the changing the IP address, netmask, or WAN gateway for the local WANJet appliance, defining a redundant peer, enabling congestion control, and adding subnets. Any values displayed on the Local WANJet appliance screen are likely the ones that you specified during initial configuration using the LCD or the Setup utility.
The subnet in which the WANJet appliance resides is automatically added to the list of local subnets (unless you clear the Include WANJet Subnet option on the Local Subnets screen). Refer to Configuring multiple subnets, for details on adding local subnets.
Important: You must replicate any changes that you make to the WANJet appliances IP address, port, or subnet address on each remote WANJet appliance to which the local WANJet appliance is connected. See Replicating configuration changes to remote WANJet appliances.
1.
In the navigation pane, expand WAN Optimization and click Local WANJet.
The Local WANJet appliance screen opens.
2.
Modify the values as required.
Table 5.1 lists and describes the local WANJet appliance settings that you can view or configure.
3.
Click the Save button.
Specifies the IP address of the local WANJet appliance. If you change this value, you must change it on each remote WANJet appliance that accesses this one.
Specifies the IP address of the LAN router (if your network configuration includes one) that resides between the WANJet appliance and the LAN. If you specify a LAN router for your local WANJet appliance, all configured local subnets use it to identify the destinations of packets.
Specifies the main port number that the local WANJet appliance uses to communicate with remote WANJet appliances. If you change this value, you must change it on each remote WANJet appliance that accesses this one.
Enables or disables a redundant peer. When enabled, this WANJet appliance connects to another WANJet appliance through the peer ports on each.
Disabled
(unchecked)
Specifies the IP address of the peer port on the local WANJet appliance. It must be in the same subnet as the redundant peer IP address.
Specifies the IP address of the peer port on the duplicate WANJet appliance. It must be in the same subnet as the self peer IP address.
Specifies the netmask of the peer and remote peer subnet. You create a subnet of the IP addresses of the peer ports on the WANJet appliance and the redundant peer.
Specifies, when checked (enabled), that the WANJet appliance sends less traffic when there is significant packet loss or congestion. When cleared (disabled), specifies that the WANJet appliance sends packets at full speed, regardless of network conditions.
Enabled
(checked)
Settings for Delayed Connection Acceptance
Links to a screen where you can configure whether to postpone acceptance of LAN requests from certain ports until the server connection is verified.
Link to Delayed Connection Acceptance screen
Links to a screen where you can add local subnets from which you want the WANJet appliance to accept traffic. By default, the WANJet appliance only recognizes the subnet it is in. Refer to Configuring multiple subnets, for details on adding local subnets.
Link to Local Subnets screen
If you make any changes to the IP address, port setting, or subnet address on a local WANJet appliance, you must replicate the changes everywhere they appear, including remote WANJet appliances.
For example, if you have four connected WANJet appliances named B1, B2, B3, and B4, and you log on to B1, the Configuration utility shows B1 as the local WANJet appliance and B2, B3, and B4 as its remote WANJet appliances. Therefore, if you change the IP address for B1, you must also change the IP address for B1 on the remote WANJet appliances (B2, B3, and B4) so that they match.
2.
In the navigation pane, expand WAN Optimization and click Remote WANJets.
The Remote WANJets screen opens and lists all of the remote WANJet appliances that need to be updated.
3.
Log on to each of the remote WANJet appliances listed on the Remote WANJets screen in step 2 and follow these steps:
a)
In the navigation pane, expand WAN Optimization and click Remote WANJets.
The Remote WANJets screen opens.
b)
In the IP column of the remote WANJet appliance whose settings you changed, click the IP address.
The Manage Remote WANJet screen opens.
d)
Click Save on the Remote WANJets screen.
4.
On the local WANJet appliance, check the connections to the remote WANJet appliances.
Once complete, the local WANJet appliance should be able to communicate with all connected remote WANJet appliances.
The WANJet appliance generally accepts incoming connections from the LAN, then attempts to connect with the server on the remote LAN. If the server is unreachable, the WANJet appliance closes the original client-side LAN connection. A delayed connection acceptance feature, enabled by default, postpones acceptance of LAN requests coming from ports 139 and 445 (ports used for CIFS optimization) until the server connection is verified.
You can configure the ports that will delay accepting requests. If you do not want to use this feature, clear the ports listed in the Ports box.
1.
In the navigation pane, expand WAN Optimization and click Local WANJet.
The Local WANJet screen opens.
2.
Click Settings for Delayed Connection Acceptance.
The WANJet Settings for Delayed Connection Acceptance screen opens.
3.
In the Ports box, type the numbers of any ports for which you want to delay the acceptance of a connection until verifying that the server is reachable. Separate multiple ports with a colon (for example, 139:445).
4.
Click Save to make the changes.
You can run the Setup utility at any time, even after the system is already configured. From the Welcome screen, click Run the Setup Utility. The screens you configure when running the Setup utility are also accessible on the WANJet appliance, as shown in Table 5.2.
In the navigation pane, expand System and click License.
In the navigation pane, expand System and click Platform.
In the navigation pane, expand WAN Optimization and click Local WANJet.
Whenever you are logged on to the Configuration utility, you can make changes to the settings configured using the Setup utility.
You can also configure user administration settings from the Platform Configuration screen. Refer to Managing local user accounts, for details on how to change passwords for the root and admin accounts, set up the Support account, and configure SSH access and HTTPD access to the WANJet appliance.
The following procedure provides the basic steps for configuring platform-related properties. Following this procedure are detailed descriptions on how to configure each of the platform properties.
1.
In the navigation pane, expand System, and click Platform.
The Configuration screen opens.
2.
Configure the platform property settings as needed.
For more information, see the rest of this chapter, as well as the online help.
Every WANJet appliance has a port called the Management port that you can use for out-of-band management. Out-of-band management provides a dedicated management channel (separate from the data channel) that is used for administration only. The Management port is an interface that the WANJet appliance uses to receive or send certain types of administrative traffic.
Tip: You typically configure the Management port using the LCD on the WANJet appliance hardware, or when you run the Setup utility during initial installation. You need to reconfigure the Management port only if the Management port IP address, netmask, or route has changed, or if you decide to configure the Management port at a later time.
The IP address that you assign to the Management port is typically on the management network. The Management route specifies the default management gateway. Use of the Management port is optional. If you use the Management port, you need to log on to the Configuration utility using its IP address rather than the WANJet IP address (although it is possible to use either).
The advantage of using the Management port is that it provides a way to separate the WANJet appliance management data from the data that is being optimized. You connect the Management port to a separate subnet dedicated to a management network, for example, which is a different network from the one where the WANJet appliance IP address is located, and where only administrators have access. You cannot use the Management port for normal traffic that is being optimized. Instead, the WANJet appliance always uses the TMM switch interfaces for that type of traffic. TMM switch interfaces are those interfaces controlled by the Traffic Management Microkernel (TMM) service. Refer to TMM service, for more details about this service.
We recommend configuring and using the Management port. If you do not have a management network, you still need to specify fictitious values for the Management port settings during setup. Then you log in using the WANJet IP address (also called the bridge IP). However, if you want to use Enterprise Manager to manage WANJet appliances, you must use the Management port for communication, not the WANJet IP address.
The following procedure describes how to set up the Management port from the Configuration utility if you did not configure it when you initially installed the WANJet appliance.
1.
In the navigation pane, expand System, and click Platform.
The Configuration screen opens.
2.
For the Management port settings:
In the IP Address box, type the IP address of the WANJet appliance on the management network.
In the Network Mask box, type the netmask for the Management port.
In the Management Route box, type the IP address of the default management gateway.
For procedural information on configuring the Management port using the LCD, see the Quick Start Guide for the WANJet appliance platform. For information on the way that the TMM service affects the Management port, see the description in TMM service.
Every WANJet appliance must have a host name and a host IP address. The IP address can be the same as the address that you used for the Management port, or you can assign a unique address.
You typically configure the host name and IP address for the WANJet appliance when you run the Setup utility during initial configuration. You need to modify the host name and IP address only if it has changed since you set it up.
1.
In the navigation pane, expand System, and click Platform.
The Configuration screen opens.
2.
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.
3.
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.
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.
The WANJet appliance should be set up for the correct time zone so the logs and system information reflect the correct time. You can set the time using the date command on the command line (refer to the Linux man page for details). Note that it is a good idea to configure a time server to synchronize the time on all WANJet appliances (see Configuring NTP time servers).
You typically set the time zone for the WANJet appliance when you run the Setup utility during initial configuration. You need to change it only if you move the appliance to a different time zone.
1.
In the navigation pane, expand System, and click Platform.
The Configuration screen opens.
2.
For the Time Zone setting, select the time zone that most closely represents the location of the WANJet appliance you are configuring.
To optimize the data that is sent over a network link, you need at least one pair of WANJet appliances, each running the WANJet appliance software. A remote WANJet appliance reverses the optimization process for data that is sent from the local WANJet appliance. For this configuration to work, the local WANJet appliance must be aware of the remote WANJet appliance. If you do not specify a remote WANJet appliance to receive the processed data, network traffic passes through the local WANJet appliance without being optimized.
When you initially configure the local WANJet appliance (as described in Testing connectivity) you have set up two WANJet appliances, each as a remote appliance to the other. You need to add remote WANJet appliances only if your configuration includes additional WANJet appliances, such as if you are using a hub and spoke configuration.
1.
In the navigation pane, expand WAN Optimization and click Remote WANJets.
The Remote WANJets screen opens.
2.
Click Add.
The Manage Remote WANJet appliance screen opens.
3.

Or, if you have two remote WANJet appliances that you want to set up for failover, select Redundant. (See Configuring remote redundancy and load balancing, for more information.)
4.
In the WANJet IP box, type the IP address for the remote WANJet appliance.
5.
In the Send Bandwidth box, specify the bandwidth available for packets traveling from the local WANJet appliance to the remote WANJet appliance:
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.
6.
In the Receive Bandwidth box, specify the bandwidth available for packets traveling from the remote WANJet appliance to the Local WANJet appliance:
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 WANJet Alias box, type a name for the remote WANJet appliance. The name must have fewer than 14 characters.
8.
In the WANJet Port box, type the number of the main port on which the remote WANJet appliance listens for data from the local WANJet appliance. The default port number is 3701.
Note: If you change the WANJet appliance port number, you must change the port number for this appliance on all remote WANJet appliances.
9.
In the Shared Key box, type the shared key that authenticates between the local and remote WANJet appliances. You can set a unique shared key for every pair of WANJet appliances.
10.
If you specified an IP address in the LAN Router field on the Local WANJet screen, you can select an MTU (Maximum Transmission Unit) type. The MTU is the maximum packet size in bytes that can be transmitted across a link. Select one of the following MTU types:
Direct
The value for this type is 1500 bytes, and is the most common MTU type for the IP protocol. This is the default MTU value.
VPN
The default MTU for this option is 1400 bytes.
Other
You can specify the MTU value required by your network.
