Access to internal network services without ADSL line

The landline is disappearing soon (painfully slow) so setup DDNS on our 5G connection to replace it

Updated title to reflect the actual goal - currently we use port forwarding on the router to allow access to services running on servers inside the space, to be accessed externally. This will no longer be possible when the ADSL line is removed (which bonline keep emailing us about, as copper lines are going away)

Current plan is port forwarding via a VPN. Wireguard will be setup on an external server that we run (bitfolk host that previously ran the forum software). The router will connect to it as a client, and services accessed via that.
