ipnat.conf

The ipnat.conf file contains redirection rules that specify how incoming packets are readdressed when the proxy is serving traffic transparently. Content Gateway creates the redirection rules during installation. You can modify these rules.


	Important After you modify this file, you must restart the proxy.

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).

Examples

The following example configures the ARM to readdress all incoming HTTP traffic to the Content Gateway IP address (111.111.11.1) on the Content Gateway proxy port 8080:

rdr hme0 0.0.0.0/0 port 80 -> 111.111.11.1 port 8080 tcp
