The short answer is the replication does both host to host and vra to host traffic when replicating.
When the first and only on the first full synchronisation the ESXi host with the source machine will replicate to the ESXi host with the destination machine directly.
Once the initial synchronisation complete incremental changes/sync I'm less clear but they originate on the vRA not sure if the you go target vRA or straight to target host, but I think vRA to vRA.
Hence why there are ports required for host to host, vRA to opposite side host and vRA to vRA.
Hi,
This is not correct. VR does not directly talk ESXi to ESXi.
ESXi talks LWD protocol to VR server on ports 31031 and 44046.
VR server talks NFC protocol (port 902) to target ESXi to access the target datastores. VR server uses port 80 of target ESXi to list the accessible target datastores.
If you think that some port is missing in the KB article - please provide exact numbers and corresponding parties - ESXi, VR appliance, etc. - so that the KB article can be fixed if necessary.
