Format
Each line in the ipnat.conf file must have the following format:
rdr interface 0.0.0.0/0 port dest -> ipaddress port proxy tcp|udp
where:
interface is the Ethernet interface that traffic will use to access the Content Gateway machine (for example, eth0 on Linux).
dest is the traffic destination port (for example, 80 for HTTP traffic).
ipaddress is the IP address of your Content Gateway server.
proxy is the Content Gateway proxy port (usually 8080 for HTTP traffic).
