If our FTP server needs to send files to remote servers that require the connection to be from a specific
IP, we can change the IP our server reports in the Outbound Services section. Clicking add... under
Outbound Services shows the following screen:
1 – Under Service choose FTP
2 – Under Action choose Allow always
3 – Under DMZ Users choose Single Address. In the fields that appear to the right, type the server's local
DMZ IP address.
4 – Under NAT IP, choose Single Address. In the fields that appear to the right, type the public IP
address you would like the server to report as its own.
