I usually solve this by setting up a proxy on a host accepting data from flash apps through a "known" port. Case in point, if you utilize port 80 or port 443, they're commonly completely open through normal firewalls. I'd then setup either a kernel level proxy on Linux (if serving out of that) or setup a mod_proxy declaration through an Apache webserver.
kernel proxy: http://www.overset.com/2007/07/13/simple-flash-remoting-proxy-through-linux/ Apache proxy: http://www.overset.com/2007/03/19/clustered-flash-remoting-through-coldfusion-redirection-problems/ You could also use the kernel proxy for using odd ports like DNS port. I would think the most likely port to be fully open for TCP/UDP traffic would be HTTPS on 443. Hope this helps some... -- Jim Palmer !
