pptp vpn from remote office to Watchguard Firebox III

[rotech22]

Each user at the remote office can connect to our Watchguard vpn using pptp setup on Windows networking. BUT, if one is connected and a second one tries to connect, they get an 'Error 721 - Remote computer did not respond' message.

Where is the problem? Can it be done? Will Watchguard MUVPN work instead? Do I need to use BOVPN (Branch OfficeVPN) and will that work with their D-Link DFL-300 firewall and Netgear JGS524 router?

TIA
Roger

Responses I received on other forums indicated this was an issue common to pptp connections having to do with the NAT service not being able to track the connections.

I was able to set up a MUVPN connection with the Watchguard client and successfully connect multiple simultaneous users.
