This is working for me:
map ppp0 192.168.44.0/24 -> 0/32 proxy port ftp ftp/tcp
map ppp0 192.168.44.0/24 -> 0/32 portmap tcp/udp 1024:65535

Perhaps the part that is broken is the 'my_ip_address/32' handling.
What version of NetBSD and IPF are you using?  I have not noticed this
problem on -current (1.4Z) with my ethernet/ppp nat box.

The only difference is the "-> 0/32" that I am using so you might want
to test the rule that way also.
