Looking for either L2TP or PPTP passthrough support - $150 bounty
-
I'm not trying to be "that guy", just hoping that with the right amount of money, this small bug could be squashed
Unfortunately his is not a small bug and we have already invested really a LOT of time and testing into this. From our point of view it's a freebsd issue and not a pfsense one and thus not easy to fix at our end. We have to do some more tests with the frickin package and disabled SCRUB (setting at system>advanced in newer snapshots) to see if we can work around it though.
Just for clarification, I was under the impression that this was a bug involving pptp, however NOT l2tp? Is that a correct assumption, or am I way off? For some reason I remember reading a post that said l2tp does NOT have the same limitation as pptp.

The bug is with the GRE protocol. I'm not familiar with L2TP either, if it doesn't use GRE then it shouldn't be affected.

I have many servers runing L2TP/IPSEC VPN servers (openswan+l2tpd). L2TP is another layer 2 tunneling protocol used to add authentication to ipsec encrypted data. In fact, when using L2TP/ipsec for roadwarrior connexions, ipsec encrypt the data using a PSK or a certificate over a tunneled session created with L2TP wich needs a username/login to be established. L2TP is encapsulated within UDP flows on port 1701.
The only thing to be careful with is the MTU size…since it is UDP encapsulated you have to ensure that big packets won't be fragmented, this is a server side configuration.
It's better than PPTP in all ways...I really hope that pfsense will soon have a L2TP/ipsec vpn server ;-)

Please test the frickin pptp proxy package with the recent 1.2-BETA-1 or a recent snapshot. It might work now.
-
Just did a whole bunch of testing and the frickin pptp package does not work… :'(
Well, back to IPSEC testing...
-
This doesn't seem to work for me either. Is there configuration required other than installing the package?
I'm willing to donate more to the bounty if it helps remove the limitation of one concurrent outbound PPTP connection to the same VPN server. Thanks!

Yes, you most likely need to pick the interface and click save in the GUI.
-
I also just fixed a bug. Please try Frickin again.
Thanks!

I'm getting a couple of errors when I try this after selecting the LAN interface. (I tried on both 1.2 BETA 1 and now under 1.2-BETA-1-TESTING-SNAPSHOT-06-06-2007) :

Thanks for any help with this. -
I removed that "is installed but not configured" message so you are still on the old version.

Sorry, do you mean the system version? I got these errors running 1.2-BETA-1-TESTING-SNAPSHOT-06-06-2007
built on Wed Jun 6 21:37:28 EDT 2007. However, I did restore my backup xml config from 1.2-BETA-1 after the upgrade to the newer snapshot. Would the restore have caused the version problem? Or did you mean that I need a newer version of the package? If so, how do I get that other than reinstalling it through the package manager?Thanks again.
-
Newer version of the package. Uninstall the package and reinstall it.

Hello!
I can add some "not working" information to this thread.
Everything works very well until someone else from the LAN does a PPTP connection. After another machine has connected and disconnected a PPTP session my machine can't connect to any PPTP server. Reboot of pfSense solves the problem and I can connect again.
I've experimented with PPTP for the last couple of days, and I can't get multiple client connections out through pfSense to work as it should.
I'm running:

We just tested the new Frickin proxy with the newest snapshot, and it still does not appear to be functioning. Has ANYONE gotten this to work yet? My bounty still stands! Thanks.
