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.

Management Port
You can now manage the WANJet appliance through the management network interface port. You can configure the management network interface port parameters from the LCD panel or from the serial console port.

Common Internet File Sharing (CIFS)
The WANJet appliance now accelerates CIFS file copies (read and write), directory browsing, and remote file access for a variety of document formats. For the WANJet appliance to accelerate CIFS files, the Optimization Policy must have the following settings for ports 139 and 445:

  • The Processing Mode is set to ACM5.
  • Connection Intercept is enabled.

Adaptive compression
The WANJet appliance maximizes WAN throughput automatically for all WAN link speeds by detecting the speed of the WAN link and adjusting its compression algorithm accordingly. High compression ratios are achieved for low-bandwidth links where the link is the bottleneck, whereas CPU cycles are not wasted on achieving these high rations on high-bandwidth links where CPU cycles are the bottleneck.

Non-transparent proxy
The WANJet appliance uses its IP address as the source address when connecting to hosts on the LAN, rather than using the remote host originating the connection.

Optimization of General Routing Encapsulated (GRE) data
You can apply the WANJet appliance's optimization techniques to data encapsulated in GRE tunnels.

Increased capacity
The previous limits on connections that the WANJet appliance can optimize concurrently have changed as follows:

  • WANJet 400 appliance has increased from 1000 to 14000 concurrent connections
  • WANJet 200 appliance has increased from 200 to 1000 concurrent connections

When the WANJet appliance receives connection requests beyond these limits, it passes them through without optimization.

Default password
The default password is admin.


This release includes the following fixes.

WANJet appliance reboot when system snapshot is taken (BUG3167, 25272)
The WANJet appliance no longer reboots when a system snapshot is taken.

TDR-2 and heavy load (BUG3262)
The WANJet appliance no longer resets connections when under sustained heavy load while TDR-2 is enabled.

Known issues

The following items are known issues in the current release.

Upgrading a one-arm configuration (CR61967)
Upgrading a WANJet appliance in a one-arm configuration may disable IP forwarding. To resolve this issue, set the value for ip_forwarding to 1. For instructions, see Enabling IP forwarding  in the Workarounds for known issues section.

WANJet Links light (CR61710)
The WANJet Links light on the dashboard does not monitor WANJet appliances that are set up as redundant peers; it displays only the status of the active peer.

VLAN configuration on a local WANJet (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.

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.

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.

TDR-2 optimization for concurrent connections (CR60126)
The limit of concurrent connections that TDR-2 can optimize is lower than the overall connection limit.

  • WANJet 400 appliance can optimize up to 1500 concurrent connections using TDR-2 optimization.
  • WANJet 200 appliance can optimize up to 200 concurrent connections using TDR-2 optimization.


SSL encryption implementation
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
If you want to process VLAN traffic, do not configure a LAN Router value in the Local WANJet link of the Web UI.

SNMP support
We have disabled SNMP support for this release and expect to reinstate it in a subsequent version.

CIFS connections (CR61513)
The WANJet appliance can prematurely terminate CIFS connections. This issue causes Lotus Notes users to receive delayed write error messages.

Workaround for known issues

The following section describes the workaround for the corresponding known issue listed in the known issues section.

Enabling IP forwarding (CR61967)

To enable IP forwarding
  1. To enable IP forwarding, type the following command:

    sysctl -w net.ipv4.ip_forward=1

  2. Verify that IP forwarding is properly enabled by typing the following command:

    sysctl -a | grep ip_forward

    The output should appear as follows:

    net.ipv4.ip_forward = 1
