Hopefully someone can help me with this. I have Symantec Endpoint as my firewall. If I disable the firewall totally, I can go to a PS3 on my network and see the Mezzmo media server.

If I enable the firewall, no matter what I have thought up, I get "no media server found".

I tried allowing all access to mezzmo.exe from my internal network (192.168.1.1- 192.168.1.99); allowing all access to TCP and UDP 1900 and 2869 and 53168. Nothing works if I have the firewall enabled. If I disable the firewall, everything works fine. Obviously it is a firewall issue, but I have no idea what else to do. Disabling the firewall just so I can run a media server is not an option. It's not that important.

I realize that this is probably the first time anyone has ever heard of this, of a firewall interfering with a media server, but incredibly, it is happening and any help would be greatly appreciated. I am not running Windows Firewall, I am on Windows XP, running Symantec Endpoint V11.
