Trying figure out which product to use and am looking at both the 857 and 877 but unsure if they will do the job or not.
I want users to be able to connect to a SBS2003, with routing and remote access enabled, on a private subnet 192.168.x.x through a DSL connection with static IP's using just the standard XP vpn connector and thier active directory credentials.
I want to open just the ports needed for the VPN connection, SMTP, and OWA.
Unfortunately the router/modem provided by the phone company only seems to want to handle the SMTP and OWA (am guessing it cannot pass the GRE protocols) without DMZ'ing to the server which I do not want to do.
Any suggestions here would be greatly appreciated.
