Hi

I've got a linux RH7.3 system acting as gateway for windows 2000 clients on NAT network 192.168.0.x

I've got a dialup working on the linux box with ppp web browsing, dns resolution etc all working.

on the client machines they correctly getting DHCP'ed all their information including a DNS server address of the 192.168.0.1 machine.

client machines can ping internet hosts.

client machines cannot resolve internet (or local) hostnames.  

whats up with my DNS config?

does you firewall (ipchains, iptables) or inetd (/etc/hosts.{allow,deny}) allow the connection?

bendecko,

Port 42?  I though named (or DNS server) should be listening on port 53/TCP.  What is the error message?  connection refused? or connect failed?
