Cisco 2611 with Road Runner Business Class

Hello,

I recently received a "new" Cisco 2611 to use with our new cable connection provided by Road Runner Business Class. Unfortunately, I don't know how to configure it properly.

I've got Eth0/1 as the inside port and Eth0/0 connected to the cable modem. I can connect to the router via it's internal address I assigned to Eth0/1 but I can't seem to access anything outside through the cable modem.

Any help would be greatly appreciated. How do I get it to route between the interfaces so that it will work properly?

Thank you,

Chris

What kind of speeds are you expecting to push with this router? I wouldn't expect to push more than 4-5Mbps through it doing NAT.

It sounds like you are doing a basic NAT setup?

Look at the Configuration Examples in

4 - 5Mbps is acceptable .. its better than the 1/4 T1 we had

I'm still at a loss with this router. Attached you'll see my current config

You will want to remove the first line from your configuration.

Once you do that, what happens if you try to ping an IP address on the Internet from the router?

I removed the default-gateway line and tried pinging

ping 64.233.167.99

Type escape sequence to abort. Send> > ip default-gateway 70.62.60.34

How about "sh ip route"?

Take things one step at a time. Can the router ping its' default gateway? Can a host behind the router ping the router, and then the router's default gateway?

The default-gateway statement is only for layer-2 things, not routers.

I can ping that IP from here, so if you can't ping it from your router, there's something else wrong, not accounting for the NAT at all.

Does your cable connection require PPPoE to talk? Do you have the correct default gateway? Do your interfaces show up?

Right now, you should investigate connectivity for the router out to the Net.

Everyone,

Thanks for the help. I figured out the issue.

It turns out that the following line needed to be changed:

ip route 0.0.0.0 0.0.0.0 Ethernet0/0

to

ip route 0.0.0.0 0.0.0.0

Once I did that, it routed correctly out to the world.

Thanks again,

Chris

Does anyone know what would cause the router to seemingly pause its connection for minutes at a time? I can still resolve IP addresses, ping hosts, etc, but thats the extent of my connectivity at points.

When it happens I can't browse the web, check my email, connect to an IM network, or anything else. My office staff is ready to lynch me because of these issues.
