  1. portmaster

    🏔 Love Freedom - ❌ Block Mass Surveillance

    relevant GitHub issue [0]

    We have not investigated too much into this topic - but from what we know it would probably be easier to implement a bandwidth cap than monitoring the bandwidth.

    And from a priority perspective it is likely to take a while until we get to these topics, our focus lays elsewhere at the moment.

  3. opensnitch

    OpenSnitch is a GNU/Linux interactive application firewall inspired by Little Snitch.

    right, I used to have a firewall that could whitelist apps in the 90s... iptables can't even do that as far as I know... but there is https://github.com/evilsocket/opensnitch that I still need to try (I no longer use Windows).

  4. portmaster-windows-kext

    The Windows kernel-mode driver for Portmaster integration

  5. ssh-vpn-docker

    Use ssh with OpenVPN inside the docker only

    I did something similar with docker. I ran both OpenVPN client and SSH client inside a docker, so only the SSH client would be affected by the OpenVPN controlling the container network. And by telling the SSH client to port forwarded, and by exposing the same port forward from the docker to the local computer, I could use it to travel through the VPN while all other ports on the local computer were unaffected.

    Here is my code for reference: https://github.com/yonixw/ssh-vpn-docker

  6. LuLu

    LuLu is the free open-source macOS firewall

    Open source for good measure: https://github.com/objective-see/LuLu
