Jiwezu63 Except W10's built-in VPN-client (which doesn't work for me), is there any free VPN-client-software being able to connect to the internet-box 3?
bitracer Any client that supports L2TP should work. More information here: https://www.swisscom.ch/en/residential/help/internet/vpn-server.html
Jiwezu63 Any client? can you give examples? I tried via IPad on Android Hotspot, that works fine. On Laptop with W10 via the same Hotspot, I tried with CheckpointVPN ForticlientVPN OpenVPN no success. Other clients available? regards and thks
bitracer Windows VPN client should work also, but you can try SoftEther VPN: https://sourceforge.net/projects/softether-vpn.mirror/
