Upgrading the software

To upgrade the WANJet appliance to version 4.2, 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 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 upgrade the WANJet appliance

  1. Log in to the WANJet Web UI, by typing the following address into a browser's Address line.

    https://<WANJet IP address>:10000

  2. Verify that a disk image of the new version of the WANJet software is accessible from the local computer on which you are viewing the WANJet Web UI (on CD-ROM, for example).

  3. In the navigation pane, expand System and click Upgrade & Boot Menu.
    The WANJet Boot Menu screen displays.

  4. Click the Upgrade button.
    A confirmation message displays.

New features and fixes in this release

This release includes the following new features and fixes.

New features

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

  1. From the WANJet Web UI navigation pane, expand Configuration and click Monitoring.

  2. After SNMP IP, select which IP address you want SNMP to use as the source address in response to SNMPv1 GET requests, and for sending SNMP traps. The choices are Management IP (set by default) or WANJet IP.

  3. Click Save to make the changes.

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

  1. In the WANJet Web UI navigation pane, expand Configuration and click Local WANJet.

  2. On the Local WANJet screen, select Settings for Delayed Acceptance.

  3. Check the box next to Enable to enable delayed connection acceptance (if it is not selected already).

  4. After Ports, type the numbers of any ports for which you want to delay the acceptance of a connection until verifying that the server is reachable. Separate multiple ports with colons (for example, 139:445).

  5. Click Save to make the changes.

Fixes in this release

This release includes the following fixes.

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.

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.

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.
