openvpn problems since crossgrading to busoness

[PotatoCarl]

Hi
I need to post a stupid question and hope for an intelligent answer:
I am using since long openvpn for our roadwarriors and others. That works well with the legacy setup up to 26.1. Community edition.
I tried a few times to convert it to the "new setup" but never succeeded.

Now a necessary hardware upgrade made us switch to the business editoion.
After a few hickups we got everything up and running in 25.10 business - except openvpn. There is no contact possible, client stucks at "waiting for reply"

Heres what I did:

- started the new appliance out of the box wir 25.y business
- restored backup from 25.7.
- assigned interfaces
- reboot
- installed missing plugins
- updated opnsense to 25.10

All works well, except no VPN.
Plugging tje "old" applicance in: bang. Works. Upgraded the old community to 26.x. no change except the warning that openvpn server is depreciated.

So anyone any idea what the problem might be and how to get openvpn up and running?

Also a comprehensible howto for the new openvpn interface wohld be great. I tried the path from the manual with no success whatever (the old took about 5min and worked perfectly)

Also maybe some good instructions for wireguard and the chances to operate it in china but that is off topic (and I have not tried everything with wireguard yet).

Any help will be apreaciated.

Thank you.

Not sure where the original config came from but 26.1.x compatible configs don't fully work in 25.10.x but they should work fine in 26.4 which came out today...


Cheers,
