Hi! I recently discovered this project as I wanted just a solution like this to play a really old game with a couple of friends. It is great! I also wanted to improve on a couple of things, so that is what this pull request is about.

• Build
  • Building with VS 2022 failed since the CMAKE_GENERATOR_PLATFORM flag was not supported. I now use CMAKE_SIZEOF_VOID_P instead.
• UI
  • Streamlined the UI. There is now only one window. Launching the app connects to discord directly and can accept invites.
  • Can leave, join, and host lobbies without closing and reopening the app.
• Fixes
  • The mapping from IPs to peers was not used before, if I understood the code correctly. This resulted in every packet being broadcasted which is both inefficient and may potentially break games that don't do much checks.
• Performance
  • Removed the std::vector<uint8_t> allocations when reading and writing packets. Only the WinTun allocation functions are used. Data is also not copied unnecessarily.
  • Mapping IPs to peers now only takes 2 array lookups instead of a std::map lookup (std::map uses red-black trees which are certainly slower than arrays). This is possible since the range of IPs we allocate is small and can fit in an array.

Hi, thanks for this awesome tool!

I just tried it and noticed that it requires the vcruntime140_1.dll which is included in the VC Redistributable (Link: https://aka.ms/vs/16/release/vc_redist.x64.exe).

I think it would be useful to add that piece of information to the readme.md?

So today I downloaded the x86_64 version and clicked host just to see what it did when it left a watermark on my screen the I cannot remove even when i click ok. I thought that the app would open discord itself. What I'm saying is to please make a script that checks if discord.exe is running if not to run it. I'll see if I can make a pr.

I love the idea of this application. I think it would be great if you'd look at this list to add more games: http://langamelist.com/

However, I do have some specific asks:

• Factorio
• Fistful of Frags
• Team Fortress 2
• Unreal Tournament 1999
• Unreal Tournament 2004
• Quake 3 Arena
• Command & Conquer Red Alert (Remaster or Open RA)
• Command & Conquer Red Alert 2
• Total Annihilation
• Supreme Commander: Forged Alliance
• Warcraft 2: Tides of Darkness
• Borderlands
• Borderlands 2
• Call of Duty
• Call of Duty 2
• Call of Duty 4: Modern Warfare
• Call of Duty: Modern Warfare 2
• Call of Duty: Modern Warfare 3
• Battlefield: Vietnam
• Battlefield: Bad Company 2
• Counter-Strike: Source
• Counter-Strike (1.6)
• Counter-Strike: Global Offensive

There are plenty more, but this list comes as a partial list from the link above. These are some older and newer games as well.

I was trying to create a Minecraft server to play with my friends, but using 192.168.42.2:(some port) in server section didn't work, is it something with CIDR? If not what do I do, i was just trying to create a LAN server.

Hello there!

Just wanted to try this out to let my friend access my SMB share so he could drop some files on it for me while I was taking a break. However, neither of us can ping or reach the other. I did disable my VPN (well, CloudFlare WARP isn't "exactly" a VPN) but still no luck. I can indeed see activity, but neither sending pings nor searching the network via Windows' integrated discovery feature showed the other machine in the network.

Is there a problem we overlooked? I was hosting, thus I had 192.168.42.1 whilst my friend had -.2.

Thanks and kind regards, Ingwie

Hi! I was trying this tool out with some friends in the hopes to be able to play Halo 2 Vista with local network games but the virtual adapter doesn't show up under the network adapters in the Halo 2 Vista's settings.

It does show up correctly under Windows 10's Network Connections control panel, and people can connect to it over Discord, however it's not an option in the game itself. So I wonder if there's maybe a setting/preference to this virtual adapter that makes it different from other network adapters causing it not to show up under the in game network adapter list? I've tried a few other LAN VPN services which do show up correctly in game. Any thoughts?

Thank you!

I've pulled the code and have made some optimisations for performance. Builds fine, but crashes I believe when it attempts to load DLL's.

What are the build instructions for this project?
