Other server-to-server communications
In server-to-server communication, the sending Symantec AntiVirus server picks a random port, starting at TCP 1025 and moving up from that point. From that point, traffic is returned on that random port. To allow communication to pass through a firewall or gateway, create rules to allow any port to accept TCP communication on 2967 and 38293 and to allow outbound TCP communication from ports 2967 and 38293:
TCP Allow 2967 to *
UDP Allow 38293 to *
TCP Allow * to 2967
UDP Allow * to 38293
