Hey guys,

Ok so I've seen there are a few posts regarding this and as I'm going through checking my configs, I can't seem to get this to work.   The issue is most certainly that I'm not allowing passive ports through the firewall.  My FTP client works fine internally, but externally It connects and authenticates to the server no problem, but when running List command I get failed to retrieve directory listing.  

- How can I check if passive FTP is checked in inspect?  I am using port 2121 for FTP due to Port 21 already being used with this external Address and forwarded to another PC.
- Also I have enabled passive ports 60000 - 65535 but Im obviously missing something.  
- the FTP host is in my DMZ so maybe thats part of the problem I'm not setting up my ACL correctly?

What do you need from me to help?

side note, when I have MasqueradeAddress turned on, internal or external won't work.. when masqueradeAddress is off, internal works, external doens't.  this is what maps the server to the public IP.. so the issue has to be with my firewall rules not accepting the passive ports.  I set the passive ports on the server to use 60000 - 60001.

ok I resolved it myself.  the issue was most certainly the rules.  by setting the port to a minimum 60000-60001 I just sent the proper port in the NAt Rules for the correct interface and it seems to be working outside.  It's not working inside, but I can mess with that in the morning..  possibly an issue with mapping the internal IP from the LAN to use the external IP in the passive mode..

tks all
