Not and ISP issue, same hardware on two different providers behaves the same, also on the same provider. Different hardware on the same two different providers work without issue, also on the same provider.
Quality of circuits is outstanding in all my remote locations. I'm using a hub spoke model, with a pair of Palo Alto 3000 series as the hub. Multiple spokes, all pfSense. Any pfsense running 2.2.2 has no issues (AES-256). All running 2.2.4 work fine except the pfsense official hardware firewall from the store.
I have no issues other than with this one firewall hardware. All other factors I can remove, have been removed.
CMB has I think all the details he's asked for, but I'm sure if he needs more he'll ask.
And trust that I have nothing but respect for CMB and the team at ESF. I honestly believe that pfsense is the best platform for perimeter security out there, commercial or not. The only reason I use PAN as my hub is because of executive concerns around an open source platform doing all security between all subnets, local and remote.
I'm just in an awkward position. I promised the CEO of the company that I would get him the best of the best, rather than what I usually build using spare parts, and I looked like an amateur after 2.2.2. All the technical reasons aside, he sees me handing him a black box that doesn't work as I told him it would. Meanwhile an old grinder under the desk supports 10-20 people on a regular basis and never blips.
The only reason I bought the pfsense branded hardware was because I read these forums regularly, and I see pfsense experts brag all the time about their bulletproof hardware from the pfsense store. I wanted to be one of those too because quite frankly although I have good good success with old hardware, one day I'm sure that might end (given the end user problems on these forums). :)
I'm grateful, honest!
Cheers,
