I hope someone can shed some light on this one....
I upgraded my M470 to latest firmware from the cloud and it stopped responding.
I did this to 8 other watchguards and none of them had an issue.
I arrived on site the next day to find no internet but things looked fine otherwise (BOVPN, Vlans etc all worked as expected). I rolled WG back and restored from backup and still same issue. I had my service provider flush the ARP on his Cisco (internet router) and things came up so i upgraded WG and thought that was weird and off I went.
Now Here is my new problem. I cannot email a particular server (rcmp 220.127.116.11).
Everything is showing deferred on my barracuda, so i started to investigate.
Doing a tracert to 18.104.22.168 over 30 hops shows my WG as hop1 and then nothing. It should be going to next hop in this case the gateway of my external interface. I can't figure out what the heck is going on. I even went so far as to add a static route on the WG dumping 22.214.171.124 to the external gateway but tracert stays same.
I have a ticket in to WG, but if anyone has any insight I would appreciate it!
