I've been having some problems with my office BOVPN lately, randomly the bridge between our two offices breaks. We have two identical XTM330 firewalls on both locations and both have the same configuration, done using this guide:

http://www.watchguard.com/help/docs/webui/11/en-us/content/en-us/bovpn/manual/manual_bovpn_fireware-xtm_fireware-xtm_web.html

But sometimes randomly the tunel stops working and we can't access the other office's network. Usually resetting the firewalls temporaly fixes the issue.

I got the following debug messages off both firewalls logs:

Office A firewall

Process=iked  msg=(officeAExternalIP<->officeBExternalIP)MWAN-Failback notify ikePcy=0x1078b638(officeBTunel), p1said=0xc645b540 UP

Process=iked  msg=(officeAExternalIP<->officeBExternalIP)MWAN-Failback failed to find the ikePcyGrp by ikePcy - name=officeBTunel

Office B firewall

Process=iked  msg=(officeBExternalIP<->officeAExternalIP)MWAN-Failback notify ikePcy=0x1078b638(officeATunel), p1said=0xc645b540 UP

Process=iked  msg=(officeBExternalIP<->officeAExternalIP)MWAN-Failback failed to find the ikePcyGrp by ikePcy - name=officeATunel

Does anyone know what could be causing this?
