What is a VPN?

My colleague, Sandro, has blogged previously about VPNs. It’s an excellent primer, so if you’re new to VPNs go and read his article first.

What is wireguard VPN?

WireGuard is a VPN stripped back to the bare bones. It follows the KISS principle. It leverages existing constructs in the Linux networking stack and simply adds a new network interface. The way traffic is managed to or from that interface is handled using existing tooling such as the ip suite of commands.

How does Wireguard work?

WireGuard treats every endpoint as a ‘peer’. Each peer has a unique public and private key pair that uniquely identifies that peer. Each peer connects to another peer in a point to point fashion. To authenticate each peer is configured with the opposite peer’s public key. The private keys must remain secret and should be stored securely .

Why is wireguard hard coded?

Why offer the user the ability to choose which protocols are used for data encryption when it’s highly likely the end user isn’t a cryptographer? The choices of cryptography used are hard coded and some see this as a disadvantage because any weaknesses discovered in the protocols used would require all servers and clients to be upgraded. I see this as an advantage as it forces users of WireGuard to upgrade their systems if a weakness is discovered.

What is the default port for Wireguard?

The default WireGuard port is 51820 but you can change this using the ListenPort setting. WireGuard uses UDP for all communications. We specify the content of the server_private.key as the value to PrivateKey.

Why use Wireguard?

Some people use WireGuard for container networking; for example, within a Kubernetes cluster. That might be useful if all or part of the cluster is running on-premises. WireGuard’s flexibility and low overhead even lend it to some unusual situations.

Why is persistent keep alive important?

The PersistentKeepAlive can be useful when one side is on a dynamic IP such as the client in the example. It causes the client to send a ‘keep alive’ packet every 25 seconds which ensures that the tunnel remains active . Without this, the server would be unable to send data to the client through the tunnel without the client sending data first (which would inform the server of the client’s current IP address).

How does wireguard work?

At the heart of WireGuard is a concept called Cryptokey Routing, which works by associating public keys with a list of tunnel IP addresses that are allowed inside the tunnel. Each network interface has a private key and a list of peers. Each peer has a public key. Public keys are short and simple, and are used by peers to authenticate each other. They can be passed around for use in configuration files by any out-of-band method, similar to how one might send their SSH public key to a friend for access to a shell server.

What is wireguard security?

A combination of extremely high-speed cryptographic primitives and the fact that WireGuard lives inside the Linux kernel means that secure networking can be very high-speed. It is suitable for both small embedded devices like smartphones and fully loaded backbone routers.

What is wireguard cryptography?

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.

How does a VPN work?

A VPN connection is made simply by exchanging very simple public keys – exactly like exchanging SSH keys – and all the rest is transparently handled by WireGuard . It is even capable of roaming between IP addresses, just like Mosh. There is no need to manage connections, be concerned about state, manage daemons, or worry about what's under the hood.

How to get involved in Wireguard?

What is wire guard?

WireGuard is the result of a lengthy and thoroughly considered academic process, resulting in the technical whitepaper, an academic research paper which clearly defines the protocol and the intense considerations that went into each decision.

Why does a client have an endpoint?

The client configuration contains an initial endpoint of its single peer (the server), so that it knows where to send encrypted data before it has received encrypted data. The server configuration doesn't have any initial endpoints of its peers (the clients). This is because the server discovers the endpoint of its peers by examining from where correctly authenticated data originates. If the server itself changes its own endpoint, and sends data to the clients, the clients will discover the new server endpoint and update the configuration just the same. Both client and server send encrypted data to the most recent IP endpoint for which they authentically decrypted data. Thus, there is full IP roaming on both ends.

What is a subnet in a VPN?

One important point to note here is that the subnet in the peer file refers to all the IP addresses which can be routed via that peer so if the peer only has a single IP address it must be entered as a /32 regardless of what subnet the peer believes itself to be on. If you wanted to configure a site to site VPN you would specify a range here and enable IP forwarding on both ends of the tunnel.

What are the two files that are included in a config file?

This will give us two files called private.key and public.key containing the respective keys which can be added to the config files.

What subnet do I use for DHCP?

If you do not have too many network services already set up which would be impacted by an IP address change and your network uses a common subnet such as 192.168.0.0/24, 192.168.1.0/24 it is worth adjusting your DHCP settings on your LAN to use a more uncommon subnet. This is because when you connect in from a public network your endpoint’s local IP will probably be in one of these ranges, leading to an address conflict. i.e. if your PC tries to access 192.168.1.20, your PC may route this down the tunnel or try to access that host on its local network (e.g. coffee shop WiFi). While it is possible to work around this using static routes it is a pain so, if possible, try to use an uncommon subnet on your home LAN.

How to provide full security access to your local network from remote locations?

The easiest way to provide full secure access to your local network from remote locations is using a VPN to encapsulate your traffic in an encrypted tunnel to access your local network.

Is Wireguard a good VPN?

WireGuard doesn’t support DHCP or allow username and password logins for the VPN, it has to be configured on a per-device basis and therefore might not be the ideal choice for corporate remote access VPNs. Additionally its newness and lack of security auditing make it a poor choice if you need it to protect highly sensitive information.

Why WireGuard?

When it comes to encrypting traffic between systems, there’s a wide variety of different VPN software available, some of which have been used since the 1990s. Each of them focus on different encryption algorithms and flow control strategies, alongside mechanisms for providing for secure authentication and negotiating encryption keys. Unfortunately, this complexity often translates to more problems, slower traffic, as well as fewer use cases and supported operating systems.

How to force all client traffic to the server using Wireguard?

To force all client traffic to the server using WireGuard, you would specify allowed-ips 0.0.0.0/0 in the WireGuard configuration on the client (but still use allowed-ips 172.16.0.0/16 in the WireGuard configuration on the server). Any internet requests sent to the server from the client on the VPN will be forwarded to the server's default gateway (the NGFW) for relay to the internet. Responses received by the server will then be sent to the client on the VPN.

How to make wireguard persistent?

However, a better method for making your WireGuard configuration persistent is to generate a WireGuard configuration file from wg0 and save it to the /etc/wireguard/wg0.conf file. You'll also need to copy your privatekey and publickey files to the same directory and ensure that only root has read and write permission to the contents of the /etc/wireguard/ directory.

What is wireguard encryption?

WireGuard uses high-performance strong cryptography, such as ChaCha20 (for symmetric data encryption) and Curve25519 (for asymmetric key negotiation), alongside a framework similar to Secure Shell (SSH) and Git. Moreover, it provides VPN functionality only when traffic is sent, doesn't include complex authentication mechanisms and is available for all desktop and mobile operating systems.
