I am a new UPC customer and have installed internet in my apartment - using cabletv connection. I have not been able to install my Synology NAS for external access, it was working fine in with my previous internet provider. I have read in some of the answers in this forum that a change from IPV6 to IPV4 might be recquired.
I am able to connect to the NAS when I am on the network at home.
Or is there any other configuration that I need to do?
