Hi, Ok, after some more fiddling, iptables is not working. I'd accidentally used the internet ip of the linux gateway, silly me :/ (How to make an ass of ones self ;P) Ok, the setup. This box has the external ip 196.14.166.226. My workstation is 196.14.166.22. All the traffic except stuff going to 196.14.166.0/27 goes out through a pptp-VPN. I've taken the VPN down in the mean time to try get this working... Still no luck. Configuration. #Enable forwarding in kernel echo 1 > /proc/sys/net/ipv4/ip_forward #Kill timestamps echo 0 > /proc/sys/net/ipv4/tcp_timestamps #Enable SYN Cookies echo 1 > /proc/sys/net/ipv4/tcp_syncookies The computer connects to use through a tie-line, 56kb. iptables -t nat -A PREROUTING -i ppp0 -p tcp -d 196.14.166.226 --dport 25 -j DNAT --to 192.168.0.50:25 is what I'm trying to use... Now, I need to be able to use 196.14.166.22 to connect to port 25 and then that'll port forward to 192.168.0.50:25. It just isn't working, I've tried things with SNAT, DNAT, -A FORWARD. I am not winning here folks. Please help, thanks in advance. -- William Fletcher (ultraviolet) IT Administrator, EPWeb networks. http://www.epweb.co.za/ Tel: +27 (041) 395 6800 Fax: +27 (041) 395 6818 Support: support@epweb.co.za
