IPv6 Support

VpnHood supports IPv6, but in Windows, you need to be already on the IPv6 network, so all your network traffic will be tunneled through VpnHood. In Windows, you will not have access to IPv6 sites if your network is not already configured to use IPv6. In Android, however, you will get an IPV6 address and access to all IPv6 sites regardless of your network configuration.

Run server on LAN

I want to run VPNHood on my LAN. The problem is, when it starts, it binds to my LAN address, but the key created is for my public address (192.168.x.x vs 72.x.x.x). So is it possible to make the key only for the LAN address?

IPv6 Leak Protection

Discussed in #42

^{Originally posted by mihaibarbulescu September 9, 2021}
Please consider implementing IPv6 leak protection. As far as I know, this could be done by effectively rerouting all IPv6 traffic to a “black hole” within the client device. Alternatively, the capability on server-side to tunnel IPv6 would be awesome. Thank you!

[question] Logs on Android

Hi,

I am using VpnHood on my mobile a Samsung device. At times VpnHood works fine without any issues, however, I noticed that certain times the connection drops randomly (Reconnecting at that instance works fine). Is there any way I could retrieve VpnHood logs from the device, are they stored anywhere?

How do we debug these random issues? I verified that the network is fine when the issue occurs.

Thanks in advance.

SharpPcap.dll is not included in VpnHood.Client.Device.WinDivert module

Socket Exception - Connection Refused

Environment :

Centos 7 - VPS (Contabo)
Port : 9443
Client : latest
Server : latest

Issue :

VPN connects fine, after that warning and error start's throwing at server side. VPN stays connected but unable to access most of the resources on the internet. Server logs showing connection refused for most of the requests. Don't know if it's VPS issue or something else.

Attached logs below, Please let me know. Thanks!

Certificate file name inconsistency

Hi, i was testing the project and i found that there's a ssl error, which comes from the server using local ip instead of the public ip for the cert file.

e.g. if you generate the certificate and tokens using
gen -name "vpn" -ep [server-public-ip] -maxClient 6
the pfx file will be created using the provided public ip endpoint, but on every connection the server checks for a file named with the local ip and throws an ssl error because of the missing file.

renaming the file to the local ip solves the issue, i thought this would help.

Add comprehensive diagnose

Lets check user network before try to establish connection
=>Before Connect

• Internet Ping Test using 8.8.8.8 or 1.1.1.1
• Internet DNS Test using 8.8.8.8 or 1.1.1.1

[Question] UDP through Tunnel

Hi,

I was wondering how UDP traffic is handled on the Tunnel? I am currently using TcpMode which means all the UDP traffic is sent through the TcpDatagramChannel. However on the server-side how does it handle proxying of these UDP packets to the actual resource (since in UDP there is no session per see). Does the server open a random port on which the data is sent to the actual server and closes it after a specific timeout? Appreciate some more details on this.

Same for ICMP, how is it handled.

Thanks.
