How to access Synology by hostname via VPN?

Question

VPN

In the local network, Synology opens both by IP and by the name specified in the settings. If Synology connects as a client to a VPN server, it can only be accessed by IP. The problem is that IP is dynamic.
How can I make it possible to address Synology by name through VPN?

Answer 1

DDNS, as mentioned above, and configure port forwarding on the router
