Openfire Flash comminication port

How can I edit the flash cross domain port number to be something other than 5229? Basically I want to use the policyFileURL: “xmlsocket://youropenfireserver:5229” in my SparkWeb, but since my server doesnt have this port open, I wanted to change it to someother port on My Openfire server. I am using OPENFIRE 3.5.2. Any help pls?
