I´m currently trying to setup sshtunnel on my 23.05 installation.
Manually starting the tunnel by directly issuing the ssh command works ok.
However, even a stripped down configuraiton in /etc/config/sshtunnl that is still only using items from the samples there is always causing the "server" section validation to fail.
I tried to debug that by modifying the start script and removed more and more validation logic (just for testing), but it continues to fail.
Does anybody have this up and running with 23.05 and could be so kind to provide a working config snippet?
