You want general information about IP Forwarding, including how to enable it


IP Forwarding is a feature designed for a special type of transparent proxy deployment mode. In this mode, the ProxySG is configured to act as a gateway that forwards a packet if it is addressed to the gateways interface card, but not to its IP address. If IP forwarding is turned off, the packet is rejected as being mis-addressed. This feature is disabled by default.

NOTE: When IP forwarding is enabled, be aware that the ProxySG will forward all traffic, on ports that are set to bypass, to the next hop. This traffic is not subject to proxy policy. However, the ProxySG will still continue to apply policy to traffic on ports that are set to intercept.

IP Forwarding can be enabled (or disabled) from the Management Console by going into the Management Console > Configuration tab > Network > Routing > Gateways.

IP Forwarding can be enabled (or disabled) through the CLI using the following command:
SGOS#(config)tcp-ip ip-forwarding {enable | disable}
