VPN WireGuard IPv6 Dual Stack Lite

Hello everyone,

I have a cable TV (broadband) connection via which the Internet is transmitted with telephony, Vodafone 250/50 Megabits Dual Stack Lite IPv6. So no IPv4 address from outside.

For business trips, public WLAN in hotels that are not encrypted, I wanted to establish a VPN WireGuard connection with a travel router to a server at home.

I was thinking of Brume 2 and Slate AX or Beryl AX.

From the outside I am using DynDNS MyFRITZ from the AVM FRITZ!Box 6490 Cabel router and QuckConnect or synology.me from the Synology DiskStation DS1618+.

Now I am not sure if this works, I have read in some cases that I cannot be reached from IPv4.

Because of the problem I have read that this can be solved with Tailscale ZeroTier, no idea what that is.

Who can tell me more about it?

Thank you and please excuse me for writing in German.

All the best Jens
