Hello,
I'd like to start by saying that I’m a complete beginner when it comes to networking and PCs. I had this idea in mind, and it took me three weeks to figure everything out. I’d like to share my experience for others like me who might be struggling.
I was following this guide on how to set up a VPN on windows : https://www.youtube.com/watch?app=desktop&v=iW87TiAP85s
No matter what I did (I erased everything and started over every day, sometimes with small modifications), I could connect to the VPN server, but the client had no internet connection.
The problem turned out to be the OpenVPN TAP-Windows6 adapter, which you need to share internet access with your main adapter. It wasn’t configured properly—it had a random IP, mask, and DNS. To fix this, I simply set everything to automatic mode. Once I did this, a proper configuration appeared after turning it off and back on.
Secondly, you absolutely need to add a rule in your router (or box, in my case). You can use the NAT/PAT or Forwarding option to allow UDP/TCP protocols on port 1194, both inbound and outbound, for your "server." You can use either its IP address or its hostname.
During my research, I noticed that many people faced the same issue I did: being able to connect to the VPN but having no internet access. I don’t know if you’re dealing with the same problem, but I hope this helps.
One significant drawback of Shadow PC for me is that it doesn’t have a fixed IP. Since they’re hosted in the OVH datacenter, many websites and apps treat them as VPNs or proxies. OpenVPN is a good solution to "fix" your IP, but I was wondering:
Since Shadow PC also uses IPv6, is it possible to route UDP protocols over IPv6 to the same server? This way, I could have both a fixed IPv4 and IPv6. From what I understand, with my current configuration, all IPv4 traffic goes through my VPN using UDP, but the Shadow PC still uses its IPv6. Would this cause any issues?
