I have a domain which I use for mails. I was thinking of adding a subdomain network.mydomain.com and have a docker ddns-update container connected to my registrar’s api since my IP isn’t static.
The purpose of that would be to provide myself VPN access through my OpenVPN and to have a static address for friends to connect to my game servers that I usually host.

My home network’s UPNP is disabled and I have no exposed ports other than the VPN port and 25565 which I use for all game servers and disable when it isn’t in use.
All services my home server provides are LAN only which is why I need VPN access.

With that said, are there any security risks?
