I am looking to setup two seperate networks in my house, I would like my personal/multimedia network and my work/project network. The problem is, my modem was provided by Verizon and is a firewall/router/wireless/modem. I would have rather had my Linksys RV082 in front of the verizon modem. What is the best way to split this?

also, if I am not mistaken... if I put a router between the modem and the RV082 that woud eliminate all security correct?
