I have a pptp vpn that works great between two offices. Everything is wonderful, till I attempt to forward ports for email from the outside of the vpn to a server on the inside of the vpn server. The forwarding rule I used was straight from the manual for 2.8.28 (thats what I am using).
dst-address=!216.101.xxx.xxx/32:25 action=nat to-dst-address=10.0.0.5 to-dst-port=25
when I enable this rule it kills all outside access to the router (and the vpn).
Any pointers?
