Updated Date: 07/30/2006
This release note documents the version 4.2.2 feature release of the WANJet appliance. For new customers, the software is preinstalled on 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, please refer to the WANJet User Guide.
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 4.2.2, 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 you are 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 4.2.2 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 tasks.
Note: You need to perform this procedure only if you have not previously activated the WANJet appliance license.
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 new features and fixes.
CIFS connections through SNAT devices (CR67637)
In previous releases, Windows servers randomly dropped CIFS connections when connecting through a secure network address translation (SNAT) device, such as the BIG-IP® system. The WANJet appliance now facilitates CIFS connections to Windows servers through SNAT devices.
WANJet system name in SNMP queries (CR66807)
Previously, when reviewing SNMP queries in a MIB browser, the system name of all WANJet appliances was WANJet, making it difficult to distinguish between appliances. The system name in the MIB browser is now a combination of the WANJet appliance alias and its IP address, in this format WANJet alias (IP address).
Client side WANJet data reduction statistics (CR66021)
For slow links, the WANJet appliance on the client side previously reversed the volume of optimized traffic with the decompressed LAN traffic in the Comparative Throughput report. The report now correctly displays data expansion statistics.
LAN and WAN cables reported incorrectly (CR65568)
In previous releases, when you configured a LAN router, the Diagnostics Connectivity report reversed the information concerning the LAN and WAN cables and reported an error. The report now shows the correct information: the gateway connects to eth2 (WAN), and the switch connects to eth0 (LAN).

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 packed in the shipping box may still refer to the cable as an orange cable. Refer to the updated document posted on AskF5.
