I have an 871 router at a remote site that terminates a DMVPN to our corporate network. We run Cisco phones through this tunnel to our Call Manager. I configured two DHCP pools, one for the phones and one for workstations on separate VLANs. The phones work fine and the workstations receive an IP with the external DNS servers, but cannot resolve websites. I have the workstation pool running through a gateway on VLAN1. The DNS lookups from the gateway address do not look to the DHCP pool dns-servers, but look to the name server in the router config. How can I get the DNS lookups to work for the workstations?

If you are connected to the router console or vty and doing a name lookup from the CLI, the router will use its own configured name server.

Are you able to ping the external dns server from your remote site ?

This turned out to be a NAT issue on the workstation DHCP pool. This is working properly now.
