Help Setting Up Server

I am new to OpenFire server but what I have setup so far I love. Thank you all for your hard work. I have now be tasked with making it so that people can connect to our OpenFire IM server from outside our office. I am able to do that using the standard port 5222, but what I need to do is make it so that when they are in places that only allows them internet service on Port 80 they can connect to our server and send IM back and forth. Could somebody give me a kind of a step by step on how to setup my server and then the Spark client software. Thank you very much!!

Best Regards,

David

look into sparkweb. it will allow them to use a web browser to connect to the server.
