i have two rules in my pf.conf file, "pass in all" and "pass out all"

i was having issues with getting pf working to begin with, so i went with
starting from nothing and working on up.

i have an ultrasparc ultra1 200e, with an added 4-port fast ethernet sbus
card, running "3.4 GENERIC#85 sparc64"

i have my access server on one and my workstation on two separate ports that
are different networks.

i can ping the access server from my workstation and my OBSD box, however, i
can't telnet to the access server from my workstation. i can telnet to the
access server through the OBSD box.

my pf.conf is as follows:
