Hi there,
you want to place the 1700 router in your LAN behind your Actiontec router, did I get this right?
So, you need to configure your router interface connected to the Actiontec with IP network 192.168.1.0 (i.e. IP address 192.168.1.2) and a static default route. If you want to use DNS from your Cisco 1700 in your internal networks, you can configure the router as a DNS server as well. Here is an example:
interface g0/0
ip address 192.168.1.2 255.255.255.0
no shutdown
ip route 0.0.0.0 0.0.0.0 192.168.1.1
ip dns server
ip name-server 192.168.1.1
Additionally, you need to configure static routes on the Actiontec router for your internal networks used behind the Cisco 1700, pointing to the 192.68.1.2 as next-hop address. Also, your Actiontec needs to do NAT to connect its 192.168.1.0 network to an external public network.
Hope that helped.
Cheers, Dennis
