NAT configuration Problems

[kanonfodda]

Ok, quick run down of my setup

1 Domain controller
6 Domain Computers
1 NAT computer

domain controller handles DNS and DHCP

NAT box connects using ISDN. I am unable to browse the internet with the NAT box connected, services which rely on IP address's (Messenger, Roger Wilco)work, any ideas?

I have set the default gateway and first DNS server to look at the NAT box.

Thanks in advance.

Isn't it best to have the DHCP box connect ?

it doesn't matter Cama, as long as the boxes on the network either have a) the nat box as DG or b) have a router as their DG that has the nat box as it's DG etc.

KF: your DNS is failing. look at your DNS server's logs to see what you can see. perhaps reconfigure it as a caching-only DNS server that forwards uncached requests to a 'real' DNS server somewhere on the internet.

edit: if you're running a firewall [and you are, aren't you?] you may have to specifically open udp#53. I had to on mine.

Hiya TDC, suddenly realised, NAT box was looking to internal server for DNS, not itself. Changed this and all working

Cheers guys
