ENDIAN Firewall - Incoming PPTP not working

I was using 2.1 briefly and decided to go to 2.2rc3 - i made a backup from the 2.1 box, and then used it for the 2.2 box...

After which, everything was working. I realized I had a Monowall box around, and decided to use it as a PPTP server BEHIND the firewall. I put its WAN into my DMZ & the LAN in my LAN, forwarded 1723 and GRE to it, but could not connect from outside the EFW. I can connect to the LAN side from my LAN and I can connect to the WAN side from my DMZ. In the firewall logs, I see that its being passed through (or it says it is).

2.2 is supposed to include 'PPTP Passthrough'... but I see no settings in the WebGUI that mention this (or maybe I'm not looking for some specific setting in the right place). I played with the routing and can ping from the LAN side to the PPTP server in the DMZ, so the connection should be possible, but the EFW seems to be in the way. When i get on my laptop and try, I get 'no route to host' errors.

- is it possible that using my 2.1 backup could cause issues with 2.2? I'm more than willing to provide information to anyone who can help me solve this problem, and I'm completely willing to accept that my way of laying this out is incorrect and I'd love to hear a better way to do this.

- with all this, I've noticed that I cannot use the FQDN for my public IPs from inside the LAN anymore. Nor can I used the IPs themselves. If I open RDP for example on my laptop and put in the FQDN or the outside IP that I use from outside the network to connect to my desktop, the connection fails. Previous to Endian, the connection would hit the LAN gateway and come right back into the LAN to my desktop. So... I'm wondering if I've cause the problem here somehow or this is a feature, not a bug. Everything but PPTP still works from outside the network.

Any help or comments are appreciated - Thanks.
