Does the firewall bounce when a vpn link drops and comes back??

[WiFivomFranMan]

I have a OpenVPN link to a remote lab.  This lab is on a junk circuit that goes up and down.  Which isn't a big deal by itself.  However, it seems when the vpn is resetting it impacts my other traffic that is unrelated.  You don't even see it when streaming netflix, but you'll see the facebook chat drop and reconnect.  It will also kick you out of online game.  It is super quick and comes right back but it is still an interruption.

Anyone know what the cause is?  And how to stop it?  I right I disabled the VPN and all is fine.

thanks
