Ok, I've looked at Rusty's nat howto as John suggested. Assuming the previously given example (have outbound tcp connections on port 1 be made on tcp port 2 instead), I've got the following command line based on the howto. iptables -t nat -A POSTROUTING -p tcp --sport 1 -o eth0 -j SNAT --to :2 I get no errors from iptables, but there is still no difference, it's as if I didn't put that rule in. Could someone please explain why that is, and straighten me out if I've got things wrong? Thanks. Greg -- Free domains: http://www.eu.org/ or mail dns-manager at EU.org
