Hello again,
So I have a semi-complicated setup that I'm trying to get working one piece at a time. I've also posted in another thread about load balancing, but before I get to that, I want to ensure that basic connectivity is working.
Basically what I have is a 2811 with a HWIC-4ESW that I will use to drop off LAN connections to my switches. I also have multiple (3) DSL connections that I want to share amongst all the LAN users.
For now I setup 1 of the 4ESW ports as part of a VLAN, but I think I'm missing a basic step about how to route traffic between the VLAN and the DSL connections.
2 of the DSL connections go through a modem and then into the integrated FE ports. The 3rd one goes into a WIC-1ADSL. I've tested both the modem DSL connections and am sure they are providing Internet access.
I am able to obtain a DHCP address through the 4ESW as well as telnet to the router. In addition, the router can resolve names so I think it has an Internet connection. (Pinging websites fails, but I think something else may be blocking ICMP). So it seems each part is working correctly.
I guess the question is, what am I missing so that I can access the Internet from the WAN connections through the 4ESW VLAN? Do I need a static route? A loopback address? Or I've also read something about bridging? Is it an access-list problem?
Here is the relevant parts from my running config:
