- I am not aware of bittorrent client that works entirely from scratch with this.
- The script should be run one time and then you just have to use the generated config. These configs expire after one year, so you might need to run this script again or renew the config using the official ProtonVPN dashboard.
- I'm not aware of that. But clearly Wireguard is more easy to make this work. Someone interested by a similar OpenVPN config generator might found the useful information from official client source code.
Note: NAT-PMP (Port Forwarding) configs are now availables in the official ProtonVPN dashboard!
Weirdly the option is available for free tier accounts too.
I've been reading your posts on reddit. So if I create a wireguard config with port forwarding enabled, how do I know which port is open (Linux) ? If I do sudo wg-quick up wg0, I get:
interface: wg0
public key: redacted
private key: (hidden)
listening port: 44781
fwmark: 0xca6c
Listening port does not seem to correspond to port forward.
Note: NAT-PMP (Port Forwarding) configs are now availables in the official ProtonVPN dashboard! Weirdly the option is available for free tier accounts too.
Hi, Thanks for your work ! I've stumbled here thanks to reddit while also trying to setup port forwarding with proton wireguard/openvpn. Do you reckon that the feature has (mistakenly?) been made available to free-tier users ? Given that the official website states it's a windows-only/paid-only feature (which is at least half false/outdated), I have a faint hope that it is the case.
However, I've been trying both [wg-quick + official proton config files] and [networkmanager openvpn "+pmp" in the username field] techniques but my natpmp clients keep saying the gateway is not compatible. So far I have tried :
- natpmpc
- py-natpmp
- nmap --script=nat-pmp-info (https://nmap.org/nsedoc/scripts/nat-pmp-info.html)
(The third one actually doesn't say the gateway is incompatible but I'm not sure I'm using it correctly, hence my question.)
Is there a surefire way to find out which port has supposedly been made available by proton upon connection ? So far every natpmp client i've tried just asks for an input port, which I don't have (although, like @pvanryn, I initially thought that it was the listening port given by wg-quick upon connection, since it changes with every connection and seems randomized as it should. However, external port-checkers keep saying it's closed so I'm guessing this is probably wrong.)

The feature is available when generating a wireguard config, nonetheless, in theory to really use NAT-PMP you need to be connected to a P2P servers thus the free servers cannot be used for Port forwarding.
I don't think this will change in the future.
The Nmap script only provide part of the NATPMP protocol which features a way to discover the external IP of the server, but this script can not reserve a port for you. But if it displayed the correct address (a ProtonVPN one) then you should be able to request a port mapping.
Note that you might need to specify the gateway address (most likely 10.2.0.1 -- see the wireguard config, and replace the last digit of the address field by 1) as it might try to get a port from your own router (which might provide this feature).
The input port that needed is in reality not important because ProtonVPN use a special NATPMP gateway. Nonetheless, using 0 as input port will ask for a random port to be forwarded.
Finally yes, the mapped port is completely different from your wireguard listening port.
Thank you for the detailed reply. You're probably right about them having distinct features implemented on different types of server.

I am aware that the nmap script does not do the actual port mapping, as there is another one for that purpose. However, interestingly enough after fiddling with the nmap command parameters I managed to get the following listing :
PORT STATE SERVICE
53/tcp open domain
4443/tcp open pharos
4446/tcp open n1-fwp
Guessing "fwp" could stand for "forwardport, I tried to actually map the port in question :
sudo nmap -p <listening_port> --script=nat-pmp-mapport 10.2.0.1 --script-args='op=map,pubport=4446,privport=25565,protocol=tcp'
But to no avail.

I can't get a fixed outside port. How can anyone contact me if the outside port is always changing? Same problem with natpmpc.
Is there a NATPMP client which actually woks?
It seems it worked as expected, the port you got were 46912 (for 1/3) and 38508. But please note that you cannot choose the port you get and that you should renew the port mapping at least every 60s (using the port you got previously).
Actually the first time you want a port, you should try to use port 0 (as internal and external) and then renew the port with the given one.
Also checkout this new documentation : https://protonvpn.com/support/port-forwarding-manual-setup/

See script here
[OP Edit]: This script suffers from the same limitations.
I suggest putting in the readme that you can find those headers in the request with the url 'https://account.proton.me/api/core/v4/events/latest'
Please add a license so people can legally fork it. I think adding it as a comment to the code is the best way to do it for a script like this.
(Without a license it's under copyright, so it's essentially like proprietary software but with the source code you aren't allowed to do much with being public)

Your wishes have been granted, this code is officially licensed under MIT & Apache 2.0, even though I never intended to particularly protect this piece of code. I hope this can help you ;)
I have made some small modifications to this and figure I would share back here. I added in the ability to choose local cities as well. So instead of generating a batch of US servers I can generate US-NY and US-VA for example. I also added in a sleep timer since I was running in to issues of generating too many configs.
As well I added in a simple extend argument to renew any configs to help futureproof. python script.py -extend will do as such. Same 1 minute sleep on that.
As well there is an additional script for anyone who would like to work as a possible "auto" connect for best server available from proton using wireguard. I would recommend importing all the configs to wireguard just to be able to control it from the app if needed. but not required.
https://gist.github.com/tiimk/56e88a6e5d47157dedf40e2761683cf1
If using the connect script you can run it and it will choose the best, run it again and it will choose the second best if already connected to the best. or run python connectscript.py -location=US-NY to only connect to the best server in US-NY. This will only connect to servers you have configs made for so may need some time to generate enough configs to get a wide variety.
👍 Cool additions, thank you for sharing this with everyone.
