I set up tailscale on my raspberry Pi 400 (with a Pi-hole and nextcloud) in my home network and I also connected my MacBook and iphone. So far I can access the tailscale IPs from mobile and the WLAN of my parents.
I also advertised the subnet with my raspberry and can access the local IPs to access the Pi-hole and nextcloud from mobile. However, when I am connected to a different WLAN (at my parents house) I can’t access the local IPs anymore.
I must hold it wrong, but I have no clue what I am doing wrong. Do you have an idea?
