What are a few top ways to link 2 office locations together so that office employees can share network resources relatively seamlessly. Since I am linking 2 businesses, reliability and security are highly mportant factors. A VPN connection which requires use of software like PC Anywhere is less seamless that I would like as it requires establishment of the VPN connection and then running of the PC Anywhere app, etc. Both offices have DSL internet connections and both are running peer-peer networks, so they have no outward facing NIC's. Currently both are running NetGear FWG114 routers which I believe offer some kind of router to router connection, but I need to look into this more.
