User and Pass on android?

"IPSec IKE PSK" doesn't exist on android, just google it and you'll see no results.
What's the username and password that needs to be used on android?
It's funny how you call other programs "stupid", but yours is the one I'd more trouble setting up.

How to connect Windows client correctly?

Below, there are entries for the server address, password and username. What should I put for the username? And how do I note the specific port (500/4500)? Thanks in advance.

Windows Server 2016 - No outside internet

Hi there,

I've been playing around with this, hosting it on a Windows 2016 server and connecting from my Mac. The MacBook can cannot to the VPN fine and can connect via Remote Desktop to the server whilst on the VPN, but it appears to provide no pass-through connection to the outside world using the internet connection that the server has, any ideas?

how to set client

cannot start pvpn

OSError: [Errno 98] Address already in use

UDP requests through PVPN

Hi,
I do not see UDP requests being sent to the wireguard server.
The logs show only TCP requests.
Could you please look into it.

Thank you

Remote ID

Hi there,

When configuring an IKEv2 connection on macOS, you are required to provide a remote ID alongside the PSK when connecting. Is there any way to define this in the software to add an additional layer of security beyond just a PSK?

can you explain a little more on TCP tunel - r command?

VPN not relaying any traffic

Running pvpn as a wireguard server:

$ .venv/bin/python -m pvpn -wg 51820 -v
Serving on UDP :500 :4500...
======== WIREGUARD SETTING ========
PublicKey: -----
===================================
Serving on UDP :51820 (WIREGUARD)...

I have a rule to forward all traffic to 1.2.3.4 through the wireguard interface (just for testing):
ip route add "1.2.3.4/32" dev wg0 proto static

but when I try to get a webpage hosted on that server:
$ wget 1.2.3.4

pvpn doesn't send any traffic back, it only spams verbose logs about a TCP connection from an ever increasing port:

login ('127.0.0.1', 35044) 225959148
TCP 127.0.0.1:53316 -> 162.247.224.52:80
TCP 127.0.0.1:53318 -> 162.247.224.52:80
TCP 127.0.0.1:53320 -> 162.247.224.52:80
TCP 127.0.0.1:53322 -> 162.247.224.52:80
TCP 127.0.0.1:53324 -> 162.247.224.52:80
TCP 127.0.0.1:53326 -> 162.247.224.52:80
TCP 127.0.0.1:53328 -> 162.247.224.52:80
TCP 127.0.0.1:53330 -> 162.247.224.52:80
<forever>

This is all running locally on one machine, I would expect that pvpn would simply act as a relay for the traffic. Am I misunderstanding something? Do I have a wrong configuration? I'm not really sure how the -r and -ur parameters are supposed to be used. 😞

member system ? keep track of data traffic usage?

dear sir, first of all, i want to say that it is a genius tech and you rock !

I am building a program that has a membership system. is it possible for you to develop a member system so that a administrator or a manager can monitor and keep track of the data usage of each user in a membership program ? or maybe a user tag ? if it can return the network data traffic usage of each user, it would really be wonderful.

thank you again for contributing this great product.

RuntimeError: This event loop is already running

from pvpn.pvpn.server import main

this gives runtime error as event loop is already running.
