So I’ve spent the better part of a week getting to know the cisco IOS better and still haven’t figured out how to;
1. automatically get my isp’s dns servers
2. Configure NAT so clients with local, static IP’s can surf the web.
Bascially this dsl line is our backdoor in case our primary connection fails. We replaced our old DSL modem from verizon with the 837 knowing that properly configured, the 837 will handle all our present and future needs.
Our network uses MS DHCP server and DNS as part of an active directory schema which is why the 837 must be configured WITHOUT dhcp.
To make sure the hardware is working, I have successfully surfed the internet by adding dhcp service and manually inputting verizon’s dns servers with;
!
router(config)# dns-servers xxx.xxx.xxx.xxx …
!
but obviously this is not preferred as I need it to automatically update if my ISP changes servers.
Any help would be very appreciated. I don’t have a config file to show as I’ve reset the router to its factory defaults (again). Thanks ~Rich
p.s., almost forgot – if I use a static address on my NIC and set the DNS server setting to the router’s local address, I cannot reach outside.
