Luanti/Mineclonia pf.conf

I want to open port 30000 for lan play. I have no issues in Linux (ugh) but
it keeps refusing a connection to port 30000 in OpenBSD. This my pf.conf:

set skip on lo

block return # block stateless traffic
pass # establish keep-state

# By default, do not permit remote connections to X11
block return in on ! lo0 proto tcp to port 6000:6010

# Port build user does not need network
block return out log proto {tcp udp} user _pbuild

#  GNU nano 8.7.1                     /etc/pf.conf

# See pf.conf(5) and /etc/examples/pf.conf

set skip on lo

block return    # block stateless traffic
pass            # establish keep-state

# By default, do not permit remote connections to X11
block return in on ! lo0 proto tcp to port 6000:6010

# Port build user does not need network
block return out log proto {tcp udp} user _pbuild

pass in proto tcp to any port 30000
