Error 721 VPN on GSM Network

Hi all

I have a client who can connect to his VPN via Wireless, Hard Wired connections, but when trying to connect using his Rogers WiMax (GSM, Mobilink modem) connection, he gets an error 721. This is on WinXP Pro SP2 with a D-Link DFL-300 Firewall with a Win2K server.

Again it works off-site with standard connections, but not with this GSM connection. Any ideas?

I think you will need to contact the GSM provider to confirm that they allow VPN ports through. I seem to remember issues with GRE (port 47)

I just got off the phone with Rogers, and they said that the issue is from the data plan my client has, he needs to have the "VPN option" upgrade to the account, which will give him access to a public ip instead of a private.

Not sure, the client has to call and request that information. At least I know it is not my problem :-)

Sooo... to open up the VPN option you need a 'public' IP? Uh huh - sounds like they limit the protocols in use until you pay.

Clear attempt to limit bandwidth unless you pay a premium
