I need to configure an Openfire server in a DMZ in order to allow users located in my local network, across various internal servers, to join a room hosted on an external Openfire server. Windows DNS resolution has already been configured.
What steps should I follow to properly configure the Openfire server in my local zone, the one in the DMZ, and the external server, to verify full functionality and connectivity?
Hi! XMPP servers use direct connections to other XMPP servers. They don’t typically use a ‘proxy’ of sorts (which is what you appear to be describing). Typically, one would make the Openfire server in your local zone to be directly accessible from the outside world, but I suspect that this isn’t an option for you.
You could look into the concept of ‘trunking’ (having an Openfire server act as a gateway). Maybe this allows you to achieve your goals. This configuration is documented in Openfire: Trunking Guide
Thanks a lot for your support.
