The following instructions explain how to upgrade existing WANJet appliances running version 3.1.1 and later to version 4.2.14. To upgrade the WANJet appliance, 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 Appliance Administrator 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.
Always back up your current configuration before installing the software upgrade.
https://<WANJet IP address>:10000
https://<WANJet IP address>:10000
The WANJet Status screen opens.
You can perform a remote upgrade to version 4.2.14 from version 3.1.1 or 3.1.2. If you are upgrading remotely from version 3.1.1 or 3.1.2, you must also complete the following tasks.
Note: You must activate the license before you can use the WANJet appliance to optimize traffic. You need to perform this procedure only once for each WANJet appliance.
For example, if the IP address of the appliance is 192.168.168.102, type https://192.168.168.102:10000 in the web browser. The welcome screen opens.
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.
Release 4.2.14 includes the following fixes.
Performance impact resulting from CIFS optimization (CR81190)
Previously, performance could be slower when using some Microsoft® products with Common Internet File System (CIFS) optimization. We have addressed CIFS performance issues related to opening and saving files when using Microsoft Excel® and Microsoft® Word, and issues related to Microsoft AccessTM when opening and saving database tables. These changes improve CIFS optimization performance.
CIFS buffer allocation (CR82619)
In previous releases, Common Internet File System (CIFS) buffer allocation failures could reset connections and disable optimization. In this release, the WANJet appliance now handles CIFS buffer allocation failures gracefully. Now, under heavy load, if CIFS fails to obtain a buffer, the WANJet appliance disables optimization for that file transfer; the connection persists without any interruption and continues to benefit from other WANJet appliance optimizations, such as TDR1 and TDR2. CIFS optimization for that connection resumes once buffers are available.

The following items are known issues in the current release.
TDR-2 efficiency on WANJet 200
On WANJet 200 appliances, the overall cache size for data transmitted or received is 50 MB, or 25 MB in each direction. TDR-2 efficiency may be degraded when transmitting or receiving application data sets of 25 MB or greater.
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.
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.
TDR-2 efficiency impacted by slow servers (CR65171)
TDR-2 efficiency may be degraded when transmitting data from low-performance servers.
UDP port optimization may cause problems on port 53 (CR70172)
When all UDP ports are optimized, DNS services over port 53 may fail. The workaround is to put all UDP ports into passthrough mode, and to specifically open those UDP ports you want to optimize.
Delayed Acceptance setting enabled after upgrade (CR81526)
The Delayed Acceptance setting is set to its default value of Enabled after you upgrade the WANJet appliance to a newer release, regardless of what it was set to in the previous release. If you do not want to enable delayed connection acceptance, after upgrading, click Settings for Delayed Acceptance on the Local WANJets screen, and clear the Enable box.
