Looks good to me. I have forwarded it to the Mike Frantzen @OpenBSD who
is responsible for the original code. Thanks!

Hum ... I get the portnumbers correctly. Note that the print-udp.c is an
unmodified copy from 5.1R and hence it should work as the normal tcpdump
you have from your default installation. Output of pftcpdump -in pflog0
would look like:

"16:37:04.203063 80.144.56.177.36068 > 80.131.152.57.4662: ..."

Note that the port number is separated by another dot not a colon as you
expected. Can you please check if the normal tcpdump (on a normal
interface) prints portnumbers?

MOB> Am I missing something?

Yes, the portnumbers ... obviously ;) I'll investigate.
