This is good.  Now all you need is to know the address for the gateway.  
The gateway address is where all your packets going out to the real world 
get funneled through:

/sbin/route add default gw 192.168.2.1 eth0

if that is the address of your cable modem, router, or whatever is the 
gateway device to your internet.

You can view your routes by typing:

/sbin/route -n

I use the -n option, so it won't try to resolve host names when it prints 
them out.  You should see a default route for things going to the network 
at the end.

By this time you should ping outside your network.  If you have problems 
resolving dns names, your /etc/resolv.conf is the file you can stick the 
addresses of nameservers in:

root@satellite linux # cat /etc/resolv.conf
nameserver 24.94.165.25
nameserver 24.94.163.34
nameserver 24.94.163.33
search kc.rr.com

Make sure resolv.conf is world readable, otherwise only root will be able 
to resolve names, while users will find they can't.

That should get you going.  If not, let me see what your routing table 
looks like with that route command.
