File Transfer Proxy Settings


We have recently installed Openfire and have everything working apart from file transfers. Our users are all behind individual NATs and we wanted to use the file transfer proxy to help facilitate the sending of files.

We get the following message from the server when we log in

And when we try to send files the client attempts to contact the proxy on the loop back address

The web admin console only lets us configure a port set to the default of 7777 and does not show anything about a server IP.

We do have two fqdns for our server and are connecting using the secondary one. main.company.com & of.company.com which is the only thing I can come up with that might be causing the problem.

Could anyone let me know what I’ve done wrong in setting up the server?

Hi Dave,

I wonder whether you have in your /etc/hosts file (or corresponding file on Windows) an entry localhost testserver.com

Openfire may then fail to detect the proper IP address. Also “nslookup testserver.com” on the server itself should return the proper IP address and not


I still have the same problem as described in the post of dwithnall above:

nslookup mydomain.com returns the right public ip address on the server and the /etc/hosts file on the server seems also correct.

How can I avoid that the Openfire XMPP server selects the loopback address


Nico (loopback interface) != (some ip within

Debian sets the in /etc/hosts, not sure about other distributions. See also http://www.debian.org/doc/manuals/reference/ch05.en.html#_the_hostname_resolutio n

IMHO, its not an issue with your DNS Server setup, it’s something that is configured locally on your server running openfire. Double check your hosts file, the has to come from somewhere.


java uses ipv6

fix it:



There’s a bug in the Openfire proxy plugin, that causes it to list only the first available network interface. This could cause your problem. This problem is addressed in Openfire 4.1.0. See https://issues.igniterealtime.org/browse/OF-1170
