Hello All:

We are running the following:
- FreeBSD 6.3 Release #1
- PF
- pftpx for our ftp proxy

We have several ftp servers of different flavors behind the PF firewalls and we 
are getting a lot of the following when users are trying to connect using 
passive mode.

"Server sent passive reply with unroutable address"

We're running pftpx as a daemon with no specific flags.  From a ps:

proxy         4845  0.0  0.0  1452  1100  ??  Is   27Sep08   0:02.13 
/usr/local/sbin/pftpx

Here is a sample of the rules we are using to allow traffic and to proxy.  The 
server macros are defined and working correctly.  Any help would be greatly 
appreciated.

nat-anchor "pftpx/*"
rdr-anchor "pftpx/*"
