VMware vSphere • VBR Replication between VMwares network connections needed

Hi,

I would have a question about network connection needed for replication between 2 VMwares, I know the page: ports needed but I would like to ask:

Scenario:
DC#1 - these VMs are running there
VBR, Veeam proxy, VMware#1 with vCenter for VMware#1 and also vCenter for VMware#2

DC#2 - VMware#2 without vCenter as its running in DC#1
********************
If I will do a replication from DC#1:
Backup proxy (DC#1) needs TCP 443 to be opened to vCenter#1/ESXi Servers and vCenter#2 (running in DC#1) ESXi servers (running in DC#2) but VBR itself do not need connection to DC#2 ESXi Servers?
Its enough if VBR has access via TCP 443 to vCenter#1 and #2?
Veeam proxy need port 902 to ESXi servers and DC#1 and DC#2

The way would be:
1. VBR will contact vCenter#1 and request a snapshot of CustomerVM#1
2. Veeam Proxy (DC#1) will read the VM data and copied it to DC#2 on the datastore/ESXi via NBD transport mode as no backup proxy will be present in DC#2

but as mentioned above VBR itself do not need any connection do DC#2? only the Veeam proxy (DC#1) need it?

Thank you!
