Installing Endpoint in a small PCI domain environment

I am setting up a PCI domain environment (a small one) with no more than 15 computers and 3 servers counting the Endpoint server. So I need the documentation or what are the ports I need to have opened from Symantec to the server and from the server to the 15 clients and the 2 other servers so I can get the definitions out to the clients and servers from symnatec. If I could get just those ports that would be very helpful to me thanks.
