Cannot access FTP Server from Internal when FTP behind Firewall

Cannot access FTP Server (Win2016Std) from Internal. (or from outside, when used with WordPress as a client)

FTP Server (10.0.5.15) and IIS on same server behind firewall (TMG 2010). Configured publishing rule to forward External IP (X.X,X,X) to Internal (10.0.5.15)

All firewall rules are configured. Can connect from outside by FTP client (PASV) - no problems! Do not really need to connect from LAN, but

THE PROBLEM IS:

WORPRESS SITE requires FTP Server setup on WEB Server to upload Updates from WEB Site.

When I try to ftp from WordPress it sends internal IP of the WEB Site as a client IP (10.0.5.15) not the Client IP of the Browser machine.
So, TMG does not allow internal to external loopback...

Any solution?

You need to setup the FTP server on the Wordpress site to send a masquerade address. I can't think of any FTP server software that doesn't have this option for this reason.

FTP server is setup with Support Firewall and External IP. FTP server works from any external client in Passive mode. The problem is when I do FTP request from Websitr. Web server puts internal IP as client IP. So basicaly, for firewall it look like request are coming from internal network. The WEB request not even getting to FTP server.
