I am looking at running the cable modem connection to a 2950 (outside vlan)and on the same vlan plug in the f0/0 interface of the 2600. Then plug the f0/1 interface in vlan (inside) of the 2950.
The issue I wonder about is DHCP address from the ISP. I there an IOS command to have the f0/0 interface on the 2600 pick up the DHCP address??
