Misconfigured IPSec Tunnel killed LAN side connections to pfSense

[mangaskahn]

While configuring two pfSense 2.0 firewalls I lost track of which machine I was on and accidentally configured one to tunnel to itself. I can't connect to the management interface or ssh from the LAN, however I can ssh in from the WAN. Is there a way to stop the tunnel or disable IPSec from the shell?

If you can still SSH, you can hit the web interface via a SSH tunnel and fix it. Item #6 here.

You can also manually edit the XML via SSH but that's error prone if you're not familiar with it, could really break things.
