    I change my configuration because i don't need the bridge the next months but it would nice to get this feature back in the future!

  • Is there a workaround other than downgrading pfsense?


  • Rebel Alliance Global Moderator

    Don't bridge ;)  would be my suggestion… Use a switch like every other sane person on the planet does when they need a switch port...



  • so how does a switch help me bridge a VPN tap port and a physical interface?


  • Rebel Alliance Global Moderator

    Don't tap either.. Use TUN…

    So you smited me for that - really???



  • So are bridges not supported on pfSense?



  • @johnpoz:

    There are reasons for doing this, for example being to Steam In-Home stream from a distant network using a VPN. Just because it's not the most sane thing to bridge ports on a router doesn't mean there aren't valid use cases, so don't just smack down people for doing so. There's a reason they are in pfSense. In my network I have a 10GbE card in my router and workstation, which are bridged to a bonded fiber port to my switch for the rest of the network, and a similar situation for my file server. I don't have $500 - $1k sitting around for a fancy 10GbE switch, so pfSense does my heavy lifting until I can get my hands on that beautiful Unifi 16 XG

    @MrClayPole:

    So are bridges not supported on pfSense?

    They are, but are not suggested due to things like this, and it requires your router to interact with the packet which is slower than the in-hardware stuff traditional switches have. Hopefully this is patched sooner than later, but for now stay at an older version of pfSense if you need router advertisement and IPv6.

    I use bridges just fine, aside from the issue in OP's post.
