So, for now, just put nameserver line(s) in /etc/resolv.conf corresponding to some public DNS server, probably your ISP gave you one. The same DNS server information is used to resolve names and addresses regardless of the ingress/egress interface of a given set of packets. Make sense? For now, tell all your computers to look at your ISP's DNS server for name resolution. When you get your own set up, point them all at that. > In addition to my question about DNS was what should i set the > gateway too? Same deal: Only one default route (gateway) gets set per machine. That's the place a packet goes if it doesn't appear destined for the subnet attached to either interface.
