 Go to the web interface for your IPCop box.  Go to Services/DHCP.  Enter 
either the external DNS Servers on this screen, or the local IPCop's IP 
address.  Save your settings.  Get a new IP on your workstation 
(release/renew).

DHCP can be used to specify network settings, like routes and DNS servers.  
But, if you have only enabled the DHCP server and specified the IP Range, 
then you are implying that your workstations will set the DNS values 
manually.  Use the DHCP settings page to indicate what values should be 
passed to the clients.

The correct value for your DNS server depends on how you want your network to 
run.  If you have an internal DNS server, then you should indicate the IP 
Address for this box.  Otherwise, you should indicate either the IPCop box 
(which indicates that you want to use IPCop as a caching DNS server), or the 
external IPAddress for your ISP's dns servers.  In the later case, IPCop 
would route the requests like any other packet destined for an external 
network.

Personally, I would set the Primary DNS server to be the IPCop box, and the 
secondary to the external address.  This buys you (a very little bit of) 
backup if the DNS server on either fails.
