      Hi all, I'm running PFSense Plus 25.07.1 but this issue impacts previous version and also impacts CE.
      WireGuard plugin is on V0.29_5 showing as up to date.

      When a WireGuard tunnel disconnects and reconnects it causes a performance hit on the firewall including CPU spike and Latency spikes seen on all gateways both RTT and RTTsd.

      This also impacts actual traffic routing though the firewall one example of this each time it happens if I'm in a teams call freezes and also lost works AOVPN connection etc also observe latecny spike and packet loss on client devices.

      Does anyone else see this behaviour?
      Just wondering if this is expected behaviour or something wrong with my setup?

      I tried disabling Open VPN server I have running but makes no difference.
