Today we announce that we no longer support port forwarding. New port forwards will no longer be supported, and existing ports will be removed 2023-07-01.
Just wanted to say that for most use cases there is a better way to do things than using port forwarding. And by that I mean by using something like Tailscale.
So, maybe before you start looking for an alternative to Mullvad have a look at the possibility of dropping port forwarding first and improving your security at the same time.
