I have plugged internet router to cisco switch 3550 port [Fa0/8]. and configured the port as L3 port wit no switchport command.
I ave configured te interface Fa0/8 with:
IP address DHCP
the interface picked an IP address from the Internet router.
I have configured an access list to a allow few PCs to internet.
but When I tried to configure IP NAT inside at the global config, I realized that the 3550 does not have to NAT after I typed IP ?
I also have 2600 router, but it has one fastethernet, one aux, and one console port. So if I plug the internet router to the 2600 router, then there will be no port from the router 2600 to connect to 3550 switch.
