As said there's an option in Veeam to reduce RPC range 2500-5000 but is there also an option to reduce RPC range 49152-65535 ?
You can reduce the RPC range, but it is not a Veeam setting. You need to adjust the range used for RPC by Windows through registry changes. You will need to do this on all of your Windows servers to ensure that they can communicate and you want to make sure you leave the range large enough to allow the connections a server needs. Windows uses RPC as the source port for almost all outbound network connections (web, etc) so keep that in mind.https://support.microsoft.com/en-us/hel ... -firewalls
