I have three branch offices and a main office. We are going to put a firewall in our main office and connect the outlying branch offices to it.
The question is how can I direct all traffic(inbound and outbound) to the firewall from the branch office(s)? Would it be best to use a VPN connection between the router and firewall? Or should I use a RIP and point the routers to the firewall that way?
We have ADSL, Windows Server 2K3. We will use either a SonicWall or Watch Guard firewall and I am not sure on the routers yet. Thanks!
