Codebase. Before WireGuard VPN, it was considered normal for tunneling protocols like OpenVPN to use 70,000 lines of codes which could even add up if additional cryptographic libraries are added. WireGuard radically simplified the underlying structure using only 4000 lines of code, which is much easier to troubleshoot.

Tunneling through ssh and wireguard is slower by about another 30-40%, and wireguard beats ssh head to head by about 35% in both transmit and receive. It's a very consistent and not so very surprising result, though I didn't expect wg to beat ssh by so much.

While WireGuard is generally faster, OpenVPN provides heavier security.

Technically every WireGuard tunnel is a peer to peer connection, but there are three main ways a WireGuard tunnel can be configured depending on whether or not a peer endpoint is known or defined: Site-to-Site (peer endpoint filled in on both sides) Remote Access “Server” (endpoint only filled in on remote peers)

The config files are generally stored in the /etc/wireguard folder. Create a new configuration file called wg0. conf in that folder. The configuration below will make your WireGuard server accept connections to 51820 and allow a client with the public key corresponding to the private key we made above.

Speed Comparison

In terms of speed, WireGuard and PPTP are the fastest, but OpenVPN, IKEv2, and L2TP offer decent speeds as well. WireGuard is fast because it's lightweight. The protocol can be implemented in very few lines of code, so there's much less going on in the background.

Networking. WireGuard uses only UDP, due to the potential disadvantages of TCP-over-TCP. Tunneling TCP over a TCP-based connection is known as "TCP-over-TCP", and doing so can induce a dramatic loss in transmission performance (a problem known as "TCP meltdown").

If you're required to share information or resources between intranets from different locations, such as offices, chain stores, using site to site VPN with WireGuard® can quickly help you build up your private network to connect all these places.

WireGuard requires about 4,000 lines of code versus OpenVPN's 70,000 lines of code, which makes security audits and verification much easier for researchers.

WireGuard uses state-of-the-art cryptography, like the Noise protocol framework, Curve25519, ChaCha20, Poly1305, BLAKE2, SipHash24, HKDF, and secure trusted constructions. It makes conservative and reasonable choices and has been reviewed by cryptographers.

Click on Add empty tunnel from options in Add tunnel button. Add a name for new tunnel. Write down the private key and public key generated by WireGuard. Add an IP address for your interface.

Right click on an OpenVPN configuration file (.ovpn) and select Start OpenVPN on this configuration file. Once running, you can use the F4key to exit. Once running in a command prompt window, OpenVPN can be stopped by the F4 key.

Start or Stop WireGuard Tunnel on Windows

msc . Click “Yes” to any security warning. Scroll down to the bottom and you will see the available WireGuard tunnels. Right-click and select Start or Stop, as appropriate.
