Gateway working but FTP still broken

[Scott Ehrlich <scott_(_at_)_MIT_(_dot_)_EDU>]

Now that I have a successful connection with everything else, I'm still
having problems with FTP, namely directory changes.   I can successfully
connect to FTP sites, but can't do much more after that.

Here's an example (and the problem occurs from all NAT'd boxes):

230 Guest login ok, access restrictions apply.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> ls
200 PORT command successful.
425 Can't build data connection: No route to host.
ftp>quit


Here again are my ipnat.rules:


map xl0 192.160.0.0/24 -> xl0/32 proxy port ftp ftp/tcp
map xl0 192.168.0.0/24 -> xl0/32 portmap tcp/udp 10000:20000
map xl0 192.168.0.0/24 -> xl0/32


Thanks.

Scott
