To upgrade the WANJet appliance to version 4.2.3, complete these tasks:

  • Upgrade the WANJet appliance
  • Activate the license (only required if not previously activated)
  • Save the WANJet appliance chassis serial number (if not previously saved)

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.

To activate the license

Note: You need to perform this procedure only if you have not previously activated the WANJet appliance license.

  1. In a web browser, access the Web UI using HTTPS and port 10000.
    For example, if the IP address of the appliance is, type in the web browser.
    The welcome screen opens.

Fixes in this release

This release includes the following fix.

CIFS optimization (CR67844)
In previous releases, applications that run from a network share and keep a large number of files open could interfere with Common Internet File System (CIFS) optimization. As a result, end users were intermittently disconnected from the network share. We have changed CIFS optimization on the WANJet appliance so that users running applications retain their connection in this situation.

Known issues

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.
