Could you all test by setting net.inet.ipsec.directdispatch to 0 as ermal outlined in this post? I believe this is all the same issue

I think I ran into the same problem (2.2.1-RELEASE on AMD G-T40E) and submitted a few crash dumps.

I set net.inet.ipsec.directdispatch to 0 and have not had another crash since then.

I have the exact same issue, my remote pfsense instantly crashes when I access it via remote ip. if I remote desktop to the server on the local network, I can access the box, but using ipsec and accessing the box from a different subnet the box crashes. I removed all squid and squid guard rebooted and It still crashes.

Nambi, did you try the fix that georgeman suggested??

nambi

I'm not too sure how to enter in that command.

do i add this into this the "Execute Shell command"
net.inet.ipsec.directdispatch=0

I entered this in there, but when I remote connected it still crashed I probably didn't put it in properly.

Thanks for the assistance.

System - Advanced - System Tunables

Thank you, there was no entry so i added "net.inet.ipsec.directdispatch" and set it to 0 and this fixed the issue.

Thanks for your patience.

georgeman

Go to System, Advanced and enter it as a tunable. Reboot just in case and test again

Are you on 32-bit??

nambi

yes we are running 32 bit, ,my system is capable for 64 bit, but I installed pfsesne a while back when 32 bit was the norm.
