Pfsense Site to Site with Sonicwall is Duplicating the tunnel

Networking & Firewalls
1

We created a site to site tunnel between our Sonicwall and Pfsense/Netgate firewalls. This was setup for over 6 months and working fine. Then all of the sudden we noticed the tunnels are duplicating them self on both sides. At one time there was 10 tunnels listed.

Has anyone seen this kind of behavior?

Firewalls:
PFSense on the latest build #'s
Sonicwall NSA 2700 on latest firmware.

You need to make sure all your timeouts are the same on both sides of the tunnel and only have your pfsense establishing the connection.

I’ll check the time out settings and let ya’ll know the results.
