As I was preparing for my ICND2 test yesterday, I thought maybe to get more hands-on experience with the equipment I would take my lab equipment and insert it into my home network. My setup goes as of right now:3550 -> 2621 -> cable modem. I have several test vlans configured on the L3 switch. With my current configuration I can ping from a pc plugged into the switch to the modem. I can't get out from there though. I know in all liklihood I'm missing one stupid thing. I have a default route on the switch pointing to the router, a route for my internal 10 network pointing to the switch from the router, and a default route pointing to the modem from the router. I have dhcp server configured on the swich and that hands out everything the way it's supposed to. My instincts tell me it's not NATing the way it should but to my knowledge I think it's correct.
On the router I have - ip nat inside source interface fastEthernet 0/0 overload. The interface in the command should be the one connected to the modem correct? If that's right does anyone have any ideas what else I could be missing? Thanks in advance for any help!
Solved! Go to Solution.
ok so when pinging from host can you do sh ip nat translation and see if there's a dynamic NAT translation going .
