Cisco 831 and Cox Cable

[jdannan]

I have a Cisco 831 router, and I am trying to use it with my cox cable business account and a static IP. I'm pretty new to cisco IOS, and not sure if I have everything setup correctly. Here is my running config. Can anyone give me some ideas if I am doing this right? Thanks...

Your missing your NAT information. Try adding this:

config t
ip route 0.0.0.0 0.0.0.0 interface ethernet 1 (IP address is better here)
access-list 1 permit 192.168.0.0 0.0.0.255
ip nat inside source list 1 overload
end


That should do it.

Ok, I added those lines. Some of the commands weren't exactly the same as you stated. Did I add them correctly with the correct interfaces? Thanks for the help.

Looks good. Does it work for you now?

ip nat inside source list 1 interface Ethernet0 overload"
I think the interface should be Ethernet1.

 

[jguerra81]

You may want to turn on ip routing as well.

[jdannan]

No it doesn't work, let me change the interface to eth1

Thanks for the help.

I'll let you know what happens shortly...

 

[jdannan]

I'm trying to remove the interface ethernet1 from the 'ip nat inside source list 1 interface Ethernet1 overload'

With a no before the command, is this correct? I'm getting Domain mapping in use, cannot remove.

 

[IPKONFIG]

Yes, you'll get that. You need to "clear ip nat translation" first, then remove the statement.
