PfSense VM Using NAT Crashing PIA Client on Host

[jimbob]

Hi, all.

Have any of you run into this?

Here's what I'm trying to achieve:

Virtualbox Linux VM -> Virtualbox pfSense VM (NAT'ed) -> Mac host -> PIA -> Interwebs

I'm using NAT for the pfSense VM when I'm on the road due to captive portals on hotel wifi and such. I can't provide credentials/agree to wifi ToS via the pfSense VM, so I just authenticate from my Mac and fire up my PIA client. Once I start the pfSense VM, the PIA cient on my Mac disconnects then reconnects. When I start the Linux VM, the PIA client again disconnects/reconnects. Then, whenever I generate any Internet-bound traffic from the Linux VM, the PIA client on my Mac will disconnect/reconnect a few times until it remains disconnected. If shut down the pfSense VM and have the Linux VM NAT through my Mac, I don't have any issues with the PIA client.

Are any of you doing something similar? Any thoughts on why the pfSense VM would cause problems for the PIA client?

I have submitted a case with PIA, as well.

Thanks in advance.
