If your ADSL modem can act as a DNS server, then you can point IPCop to that for DNS, but you can't point IPCop to itself (127.0.0.1) because it is only a proxy - not a full DNS server. In my view, for DNS your IPCop box should be directed to:-
- your ISP's DNS servers; or
- public DNS servers; or
- your ADSL modem which is using either of the above.
As I've already mentioned in other replies on this topic, my IPCop server uses my ISP for DNS requests. This means my ADSL modem is bypassed for DNS queries, but I'm not even sure if it could respond to DNS queries.
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
