# FTP Public Address Configuration
# Passive Mode FTP Behind a NAT
In passive mode FTP, when a client requests a passive data connection, the server responds with the IP address the client should connect to. If the server is behind a load balancer or NAT gateway you must set the FTP public address to the IP address or hostname of the forwarding appliance for passive connections to work properly.
# Specifying a Custom FTP Public Address
To specify a different FTP public address IP address or hostname:
- Open the file
/etc/filemage/config.yml(you may need to use
sudo), add the following lines to it, and then save the changes:
If you specify a hostname it will be resolved at server startup.
- Restart the server:
sudo systemctl restart filemage
