If I understand your question correctly, your computer (the
target computer for the SSH connection) will listen on port
1024 for SSH, right? In order to do this, you need to open
that port in your pf.conf, e. g.:

	pass in quick on $ext_if inet proto tcp from any to $ext_if port 1024 keep state

where xl0 is the network interface to connect to in my

Also make sure you set sshd's configuration to actually
listen on port 1024 instead of the standard one. ;-)

Regarding SSH, read for details. You'll find
much better suggestions for rules there, better than the
basic rules I provided above.
