 Posted: Mon Jul 20, 2009 1:46 pm Post subject: [SOLVED] Iptables segfault |
 |
|
Hello !
I installed gentoo on a server, and I'm trying to make it do some port forwarding...
Here is my network config : a router, a server and a simple computer. The router works fine, and right now the server too (i can see it from the outside).
Now I'd like to forward a port from the server to the simple computer, so I don't have to modify the router.
I installed iptables and run :
| Code: | iptables -t nat -A PREROUTING -d 192.168.1.40 -p tct --dport 80 -j DNAT --to-dest 192.168.1.51:80
|
But it just gives me a segmentation fault...
I tried updating everything (last time I ssh-ed to this server was in 2007...), switching to server profile, last kernel sources, I compiled every option in netfilter built-in, no change... iptables works fine with some example from the web, like blocking everthing but a few ports, but not this simple rule...
Any idea how to fix this ? Thanks !
EDIT : okay, stupid me, I just put tct instead of tcp in the line... crap...

I'm using kernel 2.6.29-r5, iptables 1.4.3.2.
If anything else is required to understand what is going wrong, please just ask... |

Okay, my fault... I was typing "-p tct" instead of "-p tcp"...
Damn, now it doesn't segfault but just doesn't give what i want...  |
