Hi Sean, Happy new year to you,
do a netstat and make sure that your software is listening on an address other than loopback or all addresses (0.0.0.0) run the following command netstat -an If you want to check active rules in pf run the following command pfctl -sr if you ever want to check your rules (in a recently edited pf.conf file run pfctl -nvvvf /etc/pf.conf if the rules returned match what you wish ..then you can commit / load them by running pfctl -vvvf /etc/pf.conf (each v increases verbosity ) Peter Hansteen and Max Stucchi have an amazing tutorial on PF https://home.nuug.no/~peter/pftutorial/#1 but they explain the concepts really well recommend the class that they do in person .. for the latest features about PF in the version of Openbsd you are running ... man pfctl or man pf.conf will help you ... I hope this helps and enjoy the Journey in OpenBSD ... It is awesome ...
