    Question Network "drops" when saving changes

    Hola. Whenever I make network setting changes and hit save, I lose network connectivity for 5-10 seconds. Is there a way to prevent that? I don't remember pfSense acting that way, so I'm hoping there's a workaround! TIA!

    Nope, that's by design. You have to restart networking whenever you make any changes in the network tab.

    That delay is pretty excessive though... what hardware are you using?

    Can Config, Network, Advanced, Block new sessions during network configuration contribute to something like that?

    It makes the problem worse... so yes. If that's enabled the restart takes longer, because you have to wait for the UVM to notice all is well before packets flow again.

    I'm using an i5 3470 and a quad port pro intel nic.

    Networking is restarted on networking changes. Restart time is dependent mostly on hard drive speed.

    This adds to the mystery. I have an SSD in there. Should be pretty speedy. Is there a way for me to diagnose this issue to find out what's causing this?

    Not that I'm aware of, you're talking about kernel performance at that point. How quickly can the kernel turn devices drivers on and off and such. There are no performance metrics at that level.

    The worst aspect of this is that all OpenVPN connections drop, and those have to timeout and restart before connections resume which may take a minute or more. I hate when I have to make a minor change, and then a whole site goes down (and even worse when I realize I made the wrong change, or need another, and have to do it again... what is it they say? "measure twice, cut once"?)

    For me, it also disconnects my PPPOE connections, which is kind of a bummer.
