internal network cannot connect to the internet via NAT

[theoprax]

Hi:

I've recently migrated to Debian etch from Win xp. Evrything is really cool in Linux and im enjoing it, but I've been having some troubles with my internal network.

Im using the Debian box as NAT/Firewall having installed dnsmasq and iptables. I think the configuration in Debian is not the problem because i can ping the debian system from windows, but I'm not sure though. The problem is that my windos box cant acces internet... can anyone help me pls!!!

thanks in advance
theo

did you set up the NAT in the iptables?
can you post your iptables script? or the output of "iptables -L -t nat" command?

thanks for answering. The output is:
pp@Debian:~$ sudo iptables -L -t nat
Password:
Chain PREROUTING (policy ACCEPT)
target prot opt source destination

Chain POSTROUTING (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

finnaly solved it... thanks anyway iwanabeguru..
This page helped me a lot:
Set up NAT with Linux and iptables - Traffic Engineering Server
by yhe way, i still think my iptables scripting is usless, so probably anyone can infect my network, if someone has a good example of iptables WITH nat forwarding included and knows how to install it, pls reply to my next post...

thanks!
