Port forwarding for Mac is in the Proton VPN Winter roadmap.
We’re planning to release an updated version compatible with the current version of the native client, as recently hinted at in our roadmap blog post: https://protonvpn.com/blog/product-roadmap-winter-2024-2025
It’s all on github 
Contact the support team if you have issues.
Later on, according to the roadmap.
Your isp provided a unique IPv6 address because your house’s internet is not shared by other people, vpn servers are shared and can only have so many ip addresses
V6 nat is standard for VPNs using IPV6.
It’s important to make sure that all traffic coming from a single VPN server looks identical and that nobody gets their actual IP leaped.
I’d also like to have the option for that, even an entire /64 or bigger for routers would’ve been awesome! And NAT64 to top it all off. Pretty much what ipv6.rs is offering, but they don’t look too reliable.
It writes the forwarded port to a file so running
cat /run/user/$UID/Proton/VPN/forwarded_port should show it if it’s not showing graphically this worked for me atleast
to clarify, I’m on wireguard and have disabled everything else… what am I doing wrong?
Unless you also bought a dedicated IP address to go with it, I foresee issues if the provider that you are using has more than 65,535 users.
Did you see the wordplay with the bold words? 
Split tunnelling for Linux is also mentioned in the Proton VPN winter roadmap), but from the wording it sounds more like a Spring release.
Yeah that’s how I currently do it.
Thanks for the response.
Is there a beta version of the CLI that could be made available for testing?
It’s required to have direct access to their server during installation. That is not possible everywhere. Any other Proton application (Windows, etc.) will be installed right after being downloaded. Does it explain?
Already done, it just respond to me to wait because the feature is not deployed for everybody. 
, it’s ok, it’s not like we’re second grade or anything. (guilt tripping ensues)
Tried it, didn’t work either
