And the dynamic DNS IP is updated on the DynDNS server when it changes? How exactly?

I have deposited the update URL in my Unifi UDMP. With that, I´m able to connect my smartphone via a VPN tunnel to my LAN. So, it should be working fine.

Hi there,

I think, I know whats going on. I have dualstack with both IPv4 and IPv6 adresses. But I use only IPv4 for portforwarding. So, IPv6 is deactivated internally.
Is there is a possibility to force IPv4 in Filezilla?

FileZilla should try all IP addresses a server URL resolves into. Having IPv6 internally disabled (meaning you will not be getting any IPv6 addresses assigned) prevents FileZilla from using it (impossible without a "from" IPv6 source address). It means that IPv4 should be already used. Maybe your used DNS resolver acts funky?

Note that hard-disabling IPv6 in Windows can prevent various OS components from working properly, as they internally communicate through IPv6. Unbinding the IPv6 component from the network configuration is OK, as it leaves the internal stuff in place.
