Hi all..
I'm trying to set up a VPN connection through two firewalls.
My network is as follows:


| Internet | - |firewall| - | DMZ | - | firewall | - | lan |

Obviously I can go from the lan through the firewall, to the DMZ and
through the firewall to the internet.. But you can't go from the DMZ
onto the lan.. Or from the internet to the lan..

I want to know if there's a way I could VPN to the lan so I can use
remotedesktop or VNC to access my computer..

My DMZ has a 192.168.1.x IP range, whilst my LAN has a 192.168.168.x
range.

If I VPN to my first firewall, I won't be able to access anything on
the lan, and if I VPN to the second, well.. I can't get past the first
one..

Anyone ever done something like this before?
 
Assuming all firewall/DMZ are VPN pass-through, what you need to do is open the port 1723 on all firewall/DMZ and forward it to the next one.
