Hello, I was wondering if it is possible to set up the ip unnumbered feature on a Cisco router 1700 S0 interface? Also what are the requirements to get the feature working properly? I want to connect the eth0 (using the ip of the serial interface) of the router to the outside interface of a pix. If it is possible, how would you route traffic from the pix to the S0? I have two additional ip address (Public) from my ISP and would like to reserves those from email and web server. Thank you.
