Settings for connection forwarding are under the Connection Forwarding Settings pane on the Connection Forwarding pane.

These options are available for configuring connection forwarding:

Enable Connection Forwarding enables connection forwarding by default on all neighbors added to the peer list.

Port specifies the port number to use as the default for the neighbor SteelHead in-path port. The default value is 7850.

Keep-Alive Interval specifies the number of seconds to use as the default interval for ping commands between neighbor SteelHeads. The default value is 1 second.

Keep-Alive Count specifies the number of tries to use as the default number of failed ping attempts before an appliance terminates a connection with a neighbor. The default value is 3.

In-Path Neighbor Failure uses the neighbor appliance to optimize new connections if the appliance fails.

For in-path deployments that use connection forwarding with WCCP, enabling this option ensures that if one appliance fails, the neighbor appliance continues to optimize new connections.

For in-path deployments that use connection forwarding without WCCP, enabling this option ensures that a SteelHead attempts to optimize new connections that are symmetrically routed, even after all of the neighbor SteelHeads on another network path failed. New asymmetrically routed connections aren’t optimized but passed through.

Multiple Interface Support enables high availability on SteelHead appliances configured with multiple in-path interfaces and using connection forwarding with another multiport SteelHead. This option makes all neighbor in-path interface IP addresses visible to each peer to ensure proper neighbor communication if the in-path0_0 interface fails.

RiOS 6.5 and later require connection forwarding in a WCCP cluster.

You must enable multiple interface support for a connection-forwarding neighbor to work with IPv6.

IPv6 Connection Forwarding allows IPv6 addresses to be entered in the Neighbor Table area of this page, in the In-Path IP Address and Additional IP Addresses fields.

Selecting this check box disallows the use of IPv4 addresses for neighbors; clearing this box disallows the use of IPv6 addresses for neighbors.
