Hi
I have a problem forwarding port 80. I can forward any ofter port, like 81
or 8080. I juse
iptables -t nat -A PREROUTING -p tcp -i eth2 -s 0/0 --dport 80 -j DNAT --to
172.16.1.7:80
to forward with, eth2 being my wan-interface and 172.16.1.7 my webserver.
It doesn't work. I can see in my apache log fil on the webser that the
request gets there, but nothing comes back.
If I try iptables -t nat -A PREROUTING -p tcp -i eth2 -s 0/0 --dport 8080
-j DNAT --to 172.16.1.7:80 and adds :8080 to my url, it works. I have -
ofcourse - disabled the webserver on my firewall host. I had it fixed one
time, but for other reasons I had to rerun my iptables-script and since
then it hasen't worked, that is why I think that it is an iptabels problem,
eventhough I can't see what should make this happen.
I have tried numerous differrent scripts to get this to work, even
iptables -A INPUT -j ACCEPT
iptables -A FORWARD -j ACCEPT
iptables -t nat -A POSTROUTING -j MASQUERADE
iptables -t nat -A PREROUTING -p tcp -i eth2 -s 0/0 --dport 80 -j DNAT --to
172.16.1.7:80
just to try it - and that too didn't work.
I am running kernel 2.4.19-pre9 and iptabels 1.2.7 on a redhat 7.3
Hope somebody have an idea, and thanks in advance.
