pf rdr (for ftp-proxy) problem

[Yiorgos Adamopoulos]

On April 9, 2005 Dmitri Nikulin posted a question about pf(4) and DFLY not
rdr-ing packets to ftp-proxy.  I can verify that with 1.3-Preview the situation
is the same, regardless of whether using inetd or tcpserver to start ftp-proxy.
Packets are never redireted, and the best descriptive error message that I got
was:

May  9 17:50:26 XXXXX ftp-proxy[947]: cannot connect to 127.0.0.1:8021 (Address already in use)
