WireGuard issues since updating to 25.10 business edition

[JamesFrisch]

Since updating to 25.10, my WireGuard RoadWarrior has an issue.
It basically keeps switching between no connection at all and perfectly fine.
When I ran a simple ping, I also see this, 20 or something packets get through without any problem, then 20 or something packets
timeout.


I myself am running WireGuard under macOS behind a OPNsense 25.7.5.

What I have tested yet to try to rule out errors:
- Using the tunnel over IPv4 or IPv6 only
- Issuing pings to google from both sides, to make sure there is no internet issue
- Pings from remote to the destination without a VPN to make sure there is on peering issue
- rebooted OPNsense
- WAN interface MTU is set left blank (I am using PPoE) and it shows "Calculated PPP MTU: 1492"
- MTU WireGuard is 1412
- Firewall normalization for WireGuard is set to 1352


I am out on ideas on where to troubleshoot further or what to do next. Am I missing something with MTU?
Any ideas from you guys?

Update: I don't know why, but the problem is gone after a few reboots.
