I've got an i386 box running 1.4.1, GENERIC kernel.

In my ipnat.conf, I've this:

map fxp0 192.168.34.0/24 -> a.b.c.145/32 portmap tcp/udp 40000:60000
map fxp0 192.168.34.0/24 -> a.b.c.145/32
# To make ftp work, using the internal ftp proxy, use:
#
map fxp0 192.168.34.0/24 -> a.b.c.145/32 proxy port ftp ftp/tcp

And that's it.  Of course, a.b.c.145 is an actual IP.

Telnet, ping, etc... work, however, the FTP proxy doesn't.

FTPing gives this:

ftp> ls
500 Illegal PORT command rejected
425 Can't build data connection: Connection refused.
ftp>

Can anyone let me know where I've lead myself astray?
