Hola,

That solved all my problems! Thank you! :)

I still didn't understand quite well what static-port does, though. In
the pf.conf manpage it says:
     static-port
           With nat rules, the static-port option prevents pf(4) from modif=
y-
           ing the source port on TCP and UDP packets.
What does it mean? Why would the source port be changed? If I specify

rdr pass on $ext_if proto { tcp, udp } to port 6112:6119 -> 192.168.0.3

shouldn't it just pass those ports to 192.168.0.3? Why would it be
changed? Is there some document I can read to learn about that stuff?
