Port redirection allows hosts on a lower security interface to connect to a particular IP address and port and to have the PIX Firewall redirect the traffic to the appropriate server on a higher security interface. The shared address can be a unique address, a shared outbound PAT address, or an address shared with the external interface. To implement port redirection, use the following command.
static [(internal_if_name, external_if_name)] {tcp|udp} {global_ip|interface} global_port
local_ip local_port [netmask mask]
