I'm purchasing a new solution software for a business that requires a hefty and secure network allowing only 8 remote locations into the servers. The servers are Dell 2.33 x 2 GHz 8 Gig RAM 1950 systems, running terminal services for up to 25 remote users in various locations. I run a high speed business class cable broadband, and I need a good recommendation for a firewall/router that will allow me to configure this to be possible. What would be the best recommendation?? And was is cost effective?
