@ysguy You should be able to find the crash in /var/log/caddy/caddy.log

Sorry I accidentally shipped master, this one should correct it for the tests: ``` root@opn-dev-01:/usr/local/etc/caddy # caddy build-info go go1.24.3 path caddy mod caddy (devel) dep github.com/mholt/caddy-l4 v0.0.0-20250519165220-8e3b9724e26a => github.com/WeidiDeng/caddy-l4...

@ysguy Thanks for testing, if you find no issues after a while just ping WeidiDeng.

@WeidiDeng The other reporter in the forum tested it as well now and it didnt crash anymore. https://forum.opnsense.org/index.php?topic=45777.msg239152#msg239152 So what you patched seems an improvement over the previous state.

@WeidiDeng Just pinging if this one here can be merged since it seems it solved at least some UDP related issues.

It seems there already is a document for this: https://docs.opnsense.org/manual/vpnet.html#migrating-from-tunnels-to-connections So I will add it there.

This setup worked really well with the NCP client on macOS. https://docs.opnsense.org/manual/how-tos/ipsec-swanctl-rw-ikev2-eap-mschapv2.html Its kinda the same as with OpenVPN, the best experience comes with an additional (commercial) client like Viscosity.

I'm sure it is possible somehow but you would need to do your own testing. Since it works with iOS it should work somehow with OSX. But given how iOS...

That is a good choice, especially when using Clients like Viscosity. It's just not worth the trouble IPsec imposes on the admin and the user in that environment.

Well there is no port... also tickets without an owner assigned get closed over time.
