Prevent NAS access through port forward

[A Former User]

Hi all

I opened port (Carddav - via Synology) 8443. But now people with mydomain.com:8443 can access my entire address book if they have my login credentials (2 way auth is not even needed, which is weird but ok). I tried multiple things in order to stop this, without any result.

What do you suggest?

Setup VPN access and get into your network that way.
