Ok, so I am wanting to connect my Cat5e cable from my modem to my battery backup, then from my battery backup to my router. I would like to do most of this wiring "in wall". So... what I was thinking is putting a Cat5e jack behind the router and another one behind the battery backup. Is there anyway that I can wire this so I could use a 2-port jack behind both both devices? What materials would I need to acomplish this? Thanks for the help!
