PPTP Passthrough
-
One of our clients uses a PPTP VPN.
We are unable to access this from within our network, if we use a secondary router we are able to access it.
I have added the following rules in both LAN and WAN.
GRE * * * * * None
TCP * * * 1723 * NoneHowever PPTP Outbound still fails.

I would work on getting your client up to speed on what is actual secure vpn in this day and age ;) PPTP has been dead for years!
What version of pfsense are you using?
Why would you need any rules on wan if your outbound to their pptp server? I am pretty sure they removed the PPTP passthru features then they removed PPTP.. If I recall when pptp goes through a nat the GRE portion there is a call id added to the headers.. Been many years since I had to work with that crap they call PPTP ;)
Good luck I guess.. If was a client of mine would be selling them on how bad pptp is and why they need to update to something current ;)

We are using 2.1.5-RELEASE (i386)
From all the research that I have done, everyone says that it is a GRE Firewall rule that is blocking it.
I added the rule to both the LAN and WAN to be sure and not luck.We swapped out the router with a Cisco unit to test and were able to connect without an issue.

2.1.5 still had pptp stuff.. So not only do you use OLD vpn protocols, you also use OLD pfsense ;) Current pfsense is 2.3.4..
Your not running pptp itself on pfsense are you? There were many issues with that and passthru if I recall. I thought the older versions that had pptp enabled on them had some pptp passthru settings that could be enabled… I would have to fire up such an old version to take a look.
