Correction to FTP Server behind PFSense *Guide / Explination*
Option 1. Use the proxy helper application.
1. The IP address used for ftp connections externally must be the WAN IP of the PFsense box (unconfirmed)
I can assert that this is not the case. I was able to port forward numerous different static WAN IP's to different FTP servers using Option 1. Otherwise a very useful Guide to FTP / NAT issues. Thanks.
Yeah that's wrong, changed that, thanks.
