Hi, My name is Eric Moyers. I am a Network Support Engineer in the Cisco Small Business Support Center. Thank you for using the Cisco Community Post Forums.
It is not possible to use it as a wireless bridge, however It would be possible to put the RV120W in router mode instead of gateway, turn off DHCP and connect a RV120 LAN port to a E2500 LAN port and use it that way. (You would lose one LAN port on each of the routers doing this.)
Thanks
