I have a tomcat server in a DMZ coming off my firewall machine. I have permitted traffic to /from port 8080 but am having some connection problems. Are there other *standard* ports needed for communications with my server process? Specifically Im trying to call URLConnection::getOutputStream() - AFAIK it doesn't ask for a specific port # so I don't think Im doing anything entirely strange with it. Communication with my server process works ok when its not across the firewall but fails otherwise (I can get info from the server but I can't send files back).
