LinuxQuestions.org - problems connecting to router/internet

Hi guys

I am trying to finish off my Debian 3.0 (woody) install and I ran into trouble with the connection to the internet. I have adsl and I connect through a router (gateway) which from windows I access as ip 10.0.0.2. When I boot with linux, I can successfully ping this address, and other addresses on the internet. When I open mozilla, I can access the gateway 10.0.0.2 (which comes with a web page for settings, which I can browse fine), but it cant see any websites outside.

Also when I run ifconfig I can see both eth0 and l0 and look normal

It could be simply that I didnt enter the right username/pwd for my isp , but
I dont know where to look for this or which utility to use to reconfigure them

my /etc/networking/interfaces file looks like

Quote:

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
auto lo
iface lo inet loopback
# The first network card - this entry was created during the Debian installation
# (network, broadcast and gateway are optional)
auto eth0
iface eth0 inet static
address 10.0.0.4
netmask 255.255.255.0
network 10.0.0.0
broadcast 10.0.0.255
gateway 10.0.0.2

So my question is which utility to use to check/reconfigure connection settings. Any hints will be welcome
