    This lists some ports required for a vcenter server to communicate with a linked vcenter server.

    List of networking ports:

    We are contemplating deploying linked vcenter instances in remote locations.

    Those locations require restrictive firewall settings.

    What ports are required to communicate between a vcenter instance and it's linked vcenter children?

    Only TCP Port 636 traffic between vcenter's is required?

    I believe there is a maximum of 10 Linked vCenter Systems permitted in the group.

    I believe it is just port 636 as your posted.

    See this KB article.

    636SSL port of the local instance for vCenter Linked Mode.
