I have had much better luck with the mfw module. If you are using the SuSE firewall package and forwarding to a different port on the same machine, it can do this. Just find the lines FW_FORWARD_TCP="" # Beware to use this! FW_FORWARD_UDP="" # Beware to use this! Read the comments above it, edit the proper values in, save the file, and as root: rcfirewall stop rcfirewall start Be sure the program listening on the redirected port is listening and away you go. If on a different port and a different machine, e-mail me off list. HTH, Jeffrey Quoting Cory Steers :

You have to use the ipportfw module with IPChains. Or, if you want to upgrade to IPTables, it's built in. I have no experience with either, but a friend has told me that he had much better luck with IPTables, than he ever did with ipportfw.

Hello everybody.

Does anyone know how I can tell IPchains to forward any packets destined for port x to port y .

Here is one way to do it /sbin/ipchains -A input -j ACCEPT -i $EXTIF -p tcp -s $UNIVERSE -d $EXTIP 80 /usr/sbin/ipmasqadm portfw -f /usr/sbin/ipmasqadm portfw -a -P tcp -L $EXTIP 80 -R $PORTFWIP 80 The above will forward requests on port 80 of EXTIP to port 80 of PORTFWIP. -- Hiren -- -------------------------------------------------------- If you haven't much education you must use your brain.

I ended up doing it with IPchains and TRANSPARENT_PROXY :) Sean ... What's a new brides' wedding night dread? Microsoft. <-> Gateway Info.
