I've solved this by not using the SnapGear VPN services at all, they seem quite irreversibly broken. The PPTP service is OK but there doesn't seem to be any way to map this to an internal network via the SnapGear. The L2TP IPSEC using a preshared secret VPN doesn't work at all and I don't have the knowledge required to set up an IPSEC connection on the SnapGear using certificates. Using Windows VPN services and forwarding the required ports meant I was set up in less than an hour. That doesn't mean I will ever get back to 2 days messing around fruitlessly with the SG640 VPN services. The firewall implementation at least seems to work as advertised.

I've been reading through, trying to learn enough to do my own VPN, and I think this may affect what you were trying to do, not entirely sure.
I have been on leave and as such did not get a chance to reply.
You need to setup the appropiate static routes when using PPTP addresses that are not on the local subnet.
Under the 'Advanced' config of the PPTP server, there are fields for the WINS & DNS addresses
Thanks for your reply, on the SG640 user interface, there is no advanced properties for the PPTP server as there is on the other models. I think the firmware that teh device is running is quite old too, which could explain some of the issues.
SecureComputing/SG640 Version 3.1.4
It didn't seem that upgrading to the latest would have fixed road warrior L2TP connection issues so I didn't persue it.
we do have a version that fixes the L2TP
would you like to try it ?
