Updated Date: 07/23/2006
This release note documents the version 4.2.1 feature release of the WANJet appliance. 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 4.2.1, 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 4.2.1 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 tasks.
Note: You need to perform this procedure only if you have not previously activated the WANJet appliance license.
Note: If automatic license activation does not work, you can use manual activation instead. On the WANJet License Details screen, next to Activation Method, select Manual and follow the directions on the screen.
Note: You need to perform this procedure only if you have not previously saved the chassis serial number in the About box.

This release includes the following fixes.
VLAN configuration on a local Series 200 WANJet appliance (CR61557)
When using the VLAN Settings link to add a VLAN to a local WANJet appliance, you can now reach the IP address configured in the WANJet appliance virtual IP through the VLAN interface.
iControl Server (Lighttpd) Error Log (CR65567)
Previously, the WANJet appliance saved the Lighttpd error log in flash memory, using a large amount of disk space. This error log is no longer saved on the WANJet appliance.
Simultaneous bidirectional file transfer (CR66075)
When simultaneously transferring large files in both directions (both to and from the server) on links with low BDP (bandwidth delay product), the transfers could fail. We have resolved this issue and bidirectional file transfers now complete correctly.
Roadmin administrator account (CR66390)
The roadmin administrator account now allows the administrator to view information on secondary and pop-up screens. The roadmin account was previously restricted from viewing secondary screens such as the QoS policy screen.
Timeout to nonexistent server (CR66434)
We have disabled exponential back-off of TCP timeouts, which could cause long timeouts for clients connecting to a server that was unavailable. Timeouts are now shorter if connecting to a server that is not available.
Loading applications from network drives (CR67073)
Users had a problem loading applications, such as PeopleSoft, from network drives when the WANJet appliance was active. We have resolved this issue, and applications now load correctly in this circumstance.

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.
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.
