I have been reading through about allowing PTPP through Firebox X500. However, there are centred around those who have users wanting to VPN IN which we already have set up through our main ISP for our staff, what we have is two client who rent out two of our office spaces and I have them set up to go through our *secondary* ISP that has a Firebox X500 on it.
What they use for thier services is they VPN into thier system, then remote desktop. Now, going straight through the router the VPN is fines, but throuh the Firebox get Error 721 which says the computer is not responding because GRE isn't enbaled? However in the Policy Manager I have PTPP Service set up for both ports 1723 and IP 47 but it still doesn't work?
I have tried NATs but I don't see how they'd help for trying to connect OUT to a VPN... Why won't my Firebox just pass the traffic through? Am I forgetting something?
