Thanks in advance.
Is it possible to run a back to back serial connection between a 2501 and 2620?
If so, what cabling would I require?
If not, is there an alternative configuration for the topology below, or should I pickup another 2620?
Purpose: simulate a WAN connection between the two routers.
Reason: one router would be dhcp client for cable modem, WAN serial to second router WAN serial, which acts as gateway for LAN.
