@george1421 Resolved: A 3rd party package in my router was intercepting my outbound FTP connections.

@george1421 When I try to manually FTP from the Primary Server to the Remote Storage Node, it connects, then it says the remote server has closed the connection, as shown below. It looks like it’s able to connect, but then the Remote Storage Node closes the connection instantly.

root@fog:~# ftp 192.168.6.223
Connected to 192.168.6.223.
421 Service not available, remote server has closed connection.

I have a primary FOG server and Storage node server on my LAN (in the same subnet), and replication works fine. However, I have another Storage node in a remote location, which the Primary server’s replication logs indicate as “Error: Cannot connect to <remote-storage-node>”.

The primary server and remote storage node can ping each other, and both firewalls on the IPSec tunnel are set to allow all traffic between the two subnets, and the firewalls are disabled on both servers.

Not sure if there’s a setting in FOG or a config I need to change to allow replication to work on servers outside of my primary server’s LAN?

Edit:
I also get this message when I check the status of the FOGImageReplicator.service
“FTP connection failed in /var/www/fog/lib/fog/fogftp.class.php on line 219”
