There are no filter rules on the network devices between the ESX and the
backup server. There is no firewall on the backup server.

I know there's an integrated firewall on the ESX server.
I just re-read the docs about ports, and I hope to understand it right.
- If I have a firewall between the backup client and  server, the
easiest thing is to compile the client with custom --with-tcpportrange
and --with-udpportrange settings, and then open these ports in the
firewall for packets that are send between client and server?
