I am using a WatchGuard Firebox X Edge firewall and would like to allow users to connect, download the VPN client software, and connect to the Firebox through RADIUS authentication. I have RADIUS set up and working, but I'm not able to connect and download the VPN software from my Firebox. The guides I have viewed show that if you connect to port 4100 of the Firebox, you should be able to download the VPN client from there. However, my connection just times out. What do I need to do to be able to download and connect via VPN? Also, I have port 443 forwarded to an Exchange server, does this mean I can't use the Mobile VPN?
