Software Release Date: 06/29/2006
Updated Date: 07/04/2006
This release note documents the version 4.2 feature release of the WANJet appliance. To review the features introduced in this release, see New features and fixes in this release. For existing customers, you can apply the software upgrade to 3.1.1 and later. For information about installing the software upgrade, please refer to Upgrading the software. For additional information about installing the software, please refer to the WANJet User Guide.
Note: F5 offers both feature releases and maintenance releases. For more information on our release policies, see Description of the F5 Networks software version number format.
This release supports the following platforms:
To verify your hardware platform type, click the About link from any screen in the WANJet appliance's Web UI.
To back up your current configuration before installing the software upgrade, complete the following steps.
https://<WANJet IP address>:10000
To upgrade the WANJet appliance to version 4.2, complete these tasks:
Important: For the WANJet appliance to function properly, TCP ports 3703, 3702, 3701, 10000, and 10001 must all be open on a firewall. Any firewalls separating the WANJet appliances must have these ports open. For specific information about configuring ports, refer to the WANJet User Guide.
Important: Version 4.0 introduced a new licensing procedure. If upgrading from version 3.1.x, you must first obtain a Base Registration Key. Do not proceed with the upgrade until you have the Base Registration Key. If you did not receive an email with a Base Registration Key, contact F5 Networks Technical Support (and be sure to have the WANJet appliance serial number) before attempting to install the software upgrade.
https://<WANJet IP address>:10000
You can perform a remote upgrade to version 4.2 from version 3.1.1 or later. If you are upgrading remotely from version 3.1.1 or 3.1.2, you must also complete the following procedures.
Note: You only need to perform this procedure if you have not previously activated the WANJet license.
Note: You only need to perform this procedure if you have not previously saved the chassis serial number in the About box.

This release includes the following new features and fixes.
This release includes the following new features.
SNMP IP address option (CR65262)
You can now explicitly specify which IP address to use for SNMP: either the Management interface IP (the default) or the WANJet data IP (also called the bridge IP).
To configure the SNMP IP address
Delayed connection acceptance (CR61057)
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.
The WANJet appliance now (by default) postpones acceptance of LAN requests coming from ports 445 and 139 until the server connection is verified. You can configure the ports that will delay accepting requests, or disable the setting, as needed. This setting is particularly useful for ports that use CIFS (that is, ports 445 and 139).
To configure delayed connection acceptance settings
Configuring eth0 in one-arm configurations (CR59438)
You can now configure settings for eth0 or eth1 in a one-arm configuration. However, we still recommend using eth1, the WAN port, for this type of configuration.
TDR-2 optimization for concurrent connections (CR60126)
TDR-2 now optimizes the same number of concurrent connections as allowed by the overall connection limit.
WANJet Links light (CR61710)
The WANJet Links light on the dashboard now monitors WANJet appliances that are set up as redundant peers.
CIFS transfer termination (CR62638, CR63695)
On the WANJet appliance, CIFS file transfers are now more robust and no longer terminate prematurely when performed in conjunction with some applications, such as MS SQL log shipping.
Optimizing all subnets (CR62756)
Checking Optimize All Subnets and later clearing this option no longer creates an inconsistent configuration file.
Copying small files (CR64024, CR63126)
The WANJet appliance now optimizes all types of small file transfers. Previously, it did not optimize all types of file transfers for files under 128K.
SNMP support (CR64022)
SNMP support was temporarily disabled in a previous release. SNMP support and traps have been reinstated in this release and operate as described in the WANJet User Guide. We have posted an updated MIB file with the Release Notes.
WANJet appliance reboot after high traffic volume (CR64567)
This release includes TDR-2 improvements and an increase in resource limits to address the root cause of the reported WANJet appliance reboot.
Connection Intercept on local subnets (CR64932)
Connection Intercept no longer intercepts connections destined for local subnets.
QoS diagnostic report does not display (CR65055)
The QoS diagnostic report now displays information concerning QoS on WANJet appliances.
Connection Intercept and passthrough connections (CR65399)
Connection Intercept no longer intercepts connections that the WANJet appliance is unable to optimize due to lack of resources.
Peer status wording correction (CR65540)
The Peer status wording now reads Present or Not present instead of Active or Not Active. This setting shows whether the communications channel between the local WANJet appliance and its peer is available, not whether the peer is active.
Connection Intercept and incomplete connections (CR65564)
Connection Intercept no longer intercepts connections when the WANJet appliance is unable to connect to the server or port.
WANJet Links diagnostic report (CR65876)
The WANJet Links diagnostic report now shows additional information about the remote WANJet appliance. To view this report, expand Reports in the navigation pane, click Diagnostics; then from the Monitoring menu, choose WANJet Links.

The following items are known issues in the current release.
Passthrough sessions (CR60178)
After a high volume of traffic passes through the WANJet appliance, the dashboard may temporarily display more passthrough sessions than are actually occurring.
Real Time Traffic report (CR61437)
The amount of network traffic shown in the Real Time Traffic report appears to repeatedly spike to twice the actual amount, in 30-second intervals.
VLAN configuration on a local Series 200 WANJet appliance (CR61557)
After using the VLAN Settings link to add a VLAN to a local WANJet appliance, you cannot reach the IP address configured in the WANJet appliance virtual IP through the VLAN interface.
SSL encryption implementation (CR64020)
SSL encryption is currently implemented only for optimized TCP traffic. In future releases, we plan to support TCP and UDP protocols for SSL encryption.
VLAN traffic and LAN router value configuration (CR64021)
If you want to process VLAN traffic, do not configure a LAN router value in the Local WANJet link of the Web UI.
GRE packets captured by tcpdump (CR64731)
When the tcpdump diagnostic tool captures Generic Routing Encapsulation (GRE) packets on the WANJet appliance, it does not decode the packets correctly.
Application QoS bandwidth (CR64742)
For an Application QoS Policy, setting the Link Bandwidth to 128 Kb/s or less may reduce FTP download speed.
TDR-2 efficiency impacted by slow servers (CR65171)
TDR-2 efficiency is degraded when transmitting data from low-performance servers.
WANJet 200 crossover cable (CR65989)
The WANJet 200 previously included an orange CAT6 crossover cable to connect the WANJet 200 to the WAN. We have replaced the orange crossover cable with a new yellow crossover cable that is RoHS compliant. The WANJet 200 Quick Start Card still refers to the cable as an orange cable.
