Hyper V Replica Broken with different network in Windows Server

Good Morning!
I have 2 clustered nodes in proxmox on network 192.168.0.0/22. Connected to vpn to another network, I have another hyper v that I would like to use as a replica server: 192.168.21.0/24. However, when I configure Replica Broken, it only lets me put addresses from the first network. How could I add a server that is on a different network? Something like creating a virtual network in hyper v? I don't know how to solve.
