basic dns question on my LAN with shared internet connection

[Fed]

Hi everyone, I'm new here and more or less at linux in general

I have spend more than 20 minutes reading the obvious search results for this issue but I found nothing that fits my little idiot issue

this is my setup at home, 1 win XP px, 1 win XP laptop, 1 fedora pc.

- WinXP PC with a 56k modem connected to internet (no broadband here )
the connection is shared and this is the gateway
LAN IP: 192.168.0.1

- the laptop takes the ip with DHCP and goes on the internet, no issues at all

- fedora pc:
LAN IP: 192.168.0.100

in the eth0 config panel (system settings > network) I have to setup the DNS and I have no clue what to put here, in fact I can't ping anything outside my LAN...I try to ping google and I get

[root@server1 ~]# ping -c 5 www.google.com
ping: unknown host www.google.com
[root@server1 ~]#

and this if try to ping google IP

[root@server1 ~]# ping -c 5 66.102.7.99
PING 66.102.7.99 (66.102.7.99) 56(84) bytes of data.

--- 66.102.7.99 ping statistics ---

[root@server1 ~]#

each pc can ping all the others...any suggestion is welcome

resolved

the file /etc/resolv.conf was empty, I wrote "nameserver 192.168.0.1" and now it's resolving correctly

thanks to all those who read this thread
