I'm a little new to Cisco tech. So i have this question:
I have a 2811 router witch by default has 2 FE ports witch can be configure 1 for WAN (ISP) and 1 for LAN (internal network). My question is this: what module / solution do i have to take to have let's say ... 2 more WAN interface. I would like to have backup lines for my internet connection, and when one becomes unavailabe the traffic will be routed on the second and so on. I'm intrested in 2 more WAN ports.
