ASR Replication

Hello FunMum,

This could be possible by ensuring the on-premises network can resolve the private endpoint's DNS name. To do this, you need to configure the private DNS zone and ensure the ASR appliance is set up with the correct network settings to route traffic through the VPN.

Additionally, make sure the Recovery Services vault has a private endpoint configured within the same VNet as the existing site-to-site connection. Then, register the appliance with the vCenter Server.

All you need to follow is choosing the same network and its settings which has made for the Site to site configuration.

Just to let you know, in a classic environment, a site-to-site VPN connection or ExpressRoute private peering is required for reprotection and failback. which you can consider the ASR replication will be possible through Site to Site tunnel.
