I have a 2811 router with a DSL connection to my ISP. On the router I can ping out to the ISP DNS server across the Dialer1 interface. But on from my Lan traffic stops at the 2811.
I do have a static route of ip route 0.0.0.0 0.0.0.0 dailer1
Also when i do the show ip route it does show the default route going out the dialer1 interface.
