I'm fairly sure you need to set up the DNS servers.  Your ISP should 
have given you a username and password  You will have already fed this 
into a configuration page for the router to get to the point where 
things looks like they are actually connected to the outside world.

In that same set of information your ISP should have given you two DNS 
server IP addresses which need to go into every machine on your network. 
   This will be your router and the PC you have connected to the router. 
  Under all Linux systems that information goes into the 
/etc/resolv.conf file.

DNS is a look up table which identifies www.google.com with the IP 
address 64.233.167.99.

You can check by pinging google, as already suggested.  Set the DNS 
server IP addresses in the router and then see if you can ping from it 
to google on 64.233.167.99.  Then put the DNS server IP addresses into 
your /etc/resolv.conf on your PC and any other machines on the network 
and check for connectivity with

ping -c 2 64.233.167.99
ping -c 2 www.google.com

Both will ping the same address, but you will only get a result from the 
second form if DNS is working throughout your network.

Given you've been able to access your router's configuration and 
management programs, I'd say your gateway address from your PC to the 
router is correct.  It should be the router's IP address (192.168.0.1 or 
whatever you are using). The gateway address on the Internet side is 
your external IP address given you by your ISP, whether DHCP or fixed.

Your router will be doing a lot of firewalling for you, but you might 
want to look at learning iptables so that you can set up your own 
firewall, or products like SmoothWall ( http://smoothwall.org/ ) for an 
idea of what's available doing the same thing with a GUI attached.

Congratulations on getting broadband btw.

Hope all that helps

Regards

Lesley
