/etc/resolv.conf contains dns settings
try resolving from linux box, but i guess the dns servers are wrong,
192.168.x.x is a local up range, unless your isp uses some lame way of
NAT (like some dsl providers do)
If the linux box frowards pings, and it forwards tcp/udp connections
(does it? try telnetting to the ip of some xternal web server, port
80, like:
$ telnet 198.186.203.20 80
GET / HTTP/1.1
host: www.debian.org
(don't forget the blank line) you should see a lot of html junk then.
if this works, tcp connections to the outside look ok, are you suere
then dns ip's are ok?
