In general, we recommend opening all outgoing TCP ports and all incoming and outgoing UDP ports for the domains mentioned (alternatively for the IP networks mentioned) for smooth operation. This allows Sdui communicate without any problems and possible errors in the firewall configuration are avoided.

Ports based on your own network ( for the named IP networks)

443, 80 / tcp


Ports in and out of your own network ( for the named IP networks)

10000-10050 / udp
