[raaudia4]

Need help trying to get to the internet using my (2) cisco 2501 routers and a cable modem. This is the configuration I'm running on the border router.I've tried everything I could think of to get to the internet. If any has any ideas or suggestions they would be greatly appreciated.
Thanx in advance

You can't assign an Ip to and interface and still use it in a nat statement. Instead use 'ip nat inside source list 3 interface eth0 overload'

Optionally you can do port redirection with
'ip nat inside source static tcp 192.168.x.x 80 24.1.1.1 80 extendable' (for a web server on port 80)

Also it's a good idea to either remove any access-lists during troubleshooting or at least add 'log' at the end then do a 'sh ip access-list' to see the statements being matched.

Hi matrix77, finally got it to work. Had to use the mac address of the computer on E0 of the router then switch to a different nic card on the computer.
