NAT is weird, when I clone its invallid.

[RobinVossen]

Well, I have a NAT network..
The one who has IPtables and makes the NAT has the IP 192.168.42.112 and the PCs within the NAT have: 192.168.1.0
So, I got 192.168.1.1 working with NAT and well it just works.
But when I tryed to enable the EXACT same thing for 192.168.1.11 it failed.
Is there maybe a really easy program to setup and maintain nat?
I really want this to work :/

Cheers,
Robin

Can you ping 192.168.42.112? How about your ISP's DNS server?

My guess would be you're relying on your ISP's DNS servers for name resolution, but the client at 192.168.1.11 is trying to get the DNS from the server you have masquerading (192.168.42.112). Have you set up DNS servers explicitly, or are you allowing it to default to 192.168.42.112?

Did you accidently setup your iptables to be too restrictive?

I can ping both the NAT (42.112) and the DNS (42.2) my resolve.conf file:
nameserver 192.168.42.2

Wierd..

I can ping both the NAT (42.112) and the DNS (42.2) my resolve.conf file:
nameserver 192.168.42.2

Wierd..

Can you give us the output of iptables-save?

[RobinVossen]

Ok, fixed it..
I found out that somebody changed the DNS.
its not 192.168.42.2 anymore. But .1
I really dont get why the people in this company dont comunicate with me..

Anyhow,
Thanks

I found out since I didnt have any Domain name Solving on the Pcs on that network.
