Openfire With Active Directory Integration Solution

Hi all, I am a very newbee to openfire server, and I want to put a proxy server in my network. Actually we have two different routed networks and I have setup a openfire in one location(subnet), able to send/receive files in local network using spark, but when attempting to send some files on remote site (spark client) it is showing initiating connection…, but chat is possible between local and remote place.

So I want to configure this local openfire server as well as proxy server but dont know how to do this, can someone please help me out with this.

Thanks.
