Have a Cisco 2811, T1 DSU/CSU interface. This is a newb question. I have a modem at home that gives off a public ip of (ie... 18.104.22.168). I only have this one public ip address.
For mere testing purposes, I was hoping to hook up my Comcast cable modem to the T1 DSU/CSU interface (with RJ-45 cable). Then on FE 0/0 configure a DHCP network. Will this work? Can this be done. If so how would you configure this on the command line.
