OPNsense Port Forwarding Issue

[akiPika]

I am switching from my Ubiquiti USG to a mini PC running OPNsense. The USG really slows down my internet speed when you really start adding firewall options.

In OPNsense, I have tried many options for port forwarding 13378 to my LAN IP, I've tried using HTTP, HTTPS, 443 and several other options, but audiobookshelf connections are still being blocked.

I was wondering if anyone here is using audiobookshelf with OPNsense and if so, how did they get port forwarding to work.

Thanks for any help!
