iptables routing for a win2k3 server
I am trying to get a debian machine that currently masquerades for the internal network to allow the win2k3 server inside the local network to serve as the vpn server for the incoming connections, but so far ive been unsuccessful.
I have tried quite a few things, such as
iptables -t nat -A PREROUTING -p tcp -m tcp -i eth0 -d 68.165.xxx.xx --dport 1723 -j DNAT --to 192.168.10.26
iptables -t nat -A PREROUTING -p tcp -m tcp -i eth0 -d 68.165.xxx.xx --dport 47 -j DNAT --to 192.168.10.26
which gets me to verifying passwords, but then it hangs , and doesnt establish the tunnel. I have fiddled with postrouting rules (and fowarding udp 500), but neither have gotten me further from that point.
Anyway, Any ideas of what I could try to get this server to work with outside clients? The iptables version is 1.2.11, on debian 3.1 - Thanks
