We're based in California and have a Firebox III/700 firewall, with about 10 VPN users, and I'm one of them. VPN connections seem to work great until now. Everyone's connection works except for mine - I'm on a trip to Washington, DC and for some reason I can't connect to the VPN.
My REAL external IP is 192.12.--.---. I've verified with the IT staff here that my network connection has unrestricted outbound access on all ports. My guess is that the 192 prefix is messing with the Firebox, but I'm not sure how or what to do about it.
Basically, when I connect to the VPN, it gets to the "Verifying username and password" stage and after about a minute, returns a 721 error (no response).
Our Firebox authenticates to a RADIUS server (Win2K server) inside our network in California. The log on the Firebox says that the Firebox is accepting the connection and assigning me to one of the PPTP slots, but nothing happens. I've been trying to figure this thing out, but I'm running out of ideas. Any help would be appreciated.
