Outgoing pptp Traffic-Flow stops after a while
After bringing up a pptp-connection to a remote network, traffic seems to be blocked after a while, but the tunnelstatus is still up.
I'm using pfsense 2.0 beta5 on my side and different fw on the other
In the Firewall-Log there are some entries with blocked gre traffic, initiated from the remote host.
So I created a rule, permitting inbound gre, but the problem continues, although the log file is fine.
I assume, that the state get lost or something like this, but my understanding of that is very little.
This error is alway occuring when connecting to a pptp-Server behind a Nat-Router.
I connected to another pptp-Server which was running directly on the remote-GW (dont know if NAT is used there, maybe not cause Server is listening on Wan-side)and the connection works well.
Very strange, but I only have this problem when using PFSense.
Any ideas, or suggestions where to start?

Please see this thread for additional information - I have the exact same issue: http://forum.pfsense.org/index.php/topic,30890.0.html

I updated on 1/19 as well and my PPTP VPN stability issue seemed to be resolved. But, as Chris stated above, I am having system lockups since the update and have had to do a hard reset on the system twice in the last 24 hours. I have been running the 2.0 Beta for over a month and this is the first time I have ever had to do a hard reset.

The lockup issue is likely separate. The forum thread for that is here: http://forum.pfsense.org/index.php/topic,32458.html
Try the suggestions in the thread if you can.

I think the problem is that I use a Bridge between LAN and OPT1. I have 3 interfaces
The WAN-Interface has of course it's own subnet.
The LAN-Interface shares the subnet with the OPT1-Interfaces via a Bridge, so the OPT1-Interface has no IP-Address only the LAN-Interface.
It's not a problem to reach via PPTP systems on the LAN-Interface, the traffic flow never stops but for systems on the OPT1-Interfaces it's different, I have to create a constant traffic - for example I ping a system behind the OPT-Interface - or the traffic flow stops after a few minutes. I still can reach systems behind the LAN-Interface when the traffic flow to the OPT1 interface stops.
