Veeam firewall traffic ESXi -> Veeam incoming port 111?

[pirx]

We are currently implementing new firewall rules and I'm seeing connections that I can not see in Veeam's used ports documentation.

For example: random ESXi hosts to Veeam Windows proxy/mount servers ports 111 (NFS/portmapper). I know that mount server provides powerNFS for instant restore etc. But the direction is from ESXi in HQ to Windows servers in a remote location (which has it's own proxy/mount server). Or other connections that not really make sense. It looks purely random and there are a lot of them.

Make sure that the correct mount server is being utilized (by default it is a repository server itself but another server could be configured for the repository during its creation).

mount servers are fixed in repository extent configuration. Still an ESXi host at location A is connecting to Veeam mount server at location B on port 111.
