I am trying to set up a 1812 router with 2 internet connections. One is a cable connection with DHCP and the other is DSL with static IP addresses. Neither ISP supports BGP for me.
I have looked at this link (http://www.cisco.com/en/US/tech/tk648/tk361/technologies_configuration_example09186a00808d2b72.shtml) but I'm still having some trouble figuring out what to do with the set up in my situation.
Any help on this would be appreciated.

Hi, you can start with a simpler configuration:
http://www.cisco.com/en/US/tech/tk648/tk361/technologies_configuration_example09186a0080950834.shtml
Then when is working you add OER, firewall, etc, as needed.

Thanks. That link makes a little more sense. The dialer interface has me a little off, but hopefully I can do something with that.

If you don't have PPP, don't configure dialer. You might have to configure a BVI instead.

Just add:
ip route 0.0.0.0 0.0.0.0
and the static NAT should not need to reference route-map. Actually not even the dynamic nat do, but cisco says otherwise in their examples.
