Ian: This is from the web interface of our ZTE ADSL Modem:

 DNS Server Configuration

If Enable Automatic Assigned DNS checkbox is selected, this router
will accept the first received DNS assignment from the PPPoA, PPPoE or
MER/DHCP enabled PVC(s) during the connection establishment. If the
checkbox is not selected, enter the primary and optional secondary DNS
server IP addresses. Click "Apply" to save it.
NOTE:  	If changing from unselected Automatic Assigned DNS to selected Automatic
Assigned DNS, you must reboot the router to get the automatic assigned DNS
addresses.

	Enable Automatic Assigned DNS


Primary DNS server: 	

Last night, I put the IP addresses for the 2 DNS Servers at opendns.com there.

Question: The next time I connect our Backup IPCop box, should I put
the 2 IP addresses for opendns.com there, or, the IP of our ADSL
Modem? Which will be faster? If I understand, you have the IP
addresses in your IPCop box and that bypasses your ADSL Modem.
TIA, Lanny
