Hi all.
I have come across documents that say UDP RTP ports 10020-10531 must be forwarded on the Firewall to the IP address in 84-26. Other mention ports 10020-10083.
1. Which one is correct?
2. Can the port range be reduced to 10020-10028 if I have 8 channels?

Source 10000-60000 to Destination 10020-10277
UDP 10000 - 60000UDP 10020 - 10277

If you reduce the port range you will have issues with audio.
