iptables redirect - Guest - 2004-01-23
A local ISP blocks port 25 so mail users cannot use my smtp server. I need to redirect port 2525 to 25 so my users can bypass this.
Ive done this on bsd servers but cant get it to stick with iptables on linux. I have use different variations but here is one of the commands i have tried:
iptables -t nat -A PREROUTING -i eth0 -p tcp -dport 2525 -j REDIRECT --to-port 25
any help would be most appreciated.
cool beans.

iptables redirect - grep420 - 2004-01-26
/sbin/iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 2525 -j DNAT --to 192.168.0.10:25
this will forward all incoming tcp traffic on the eth0 interface to port 2525 over to internal machine 192.168.0.10 on port 25
