WireGuard

How to set up WireGuard as an iOS VPN configuration in order to tunnel all traffic from an iOS or iPadOS device through a Linux server.

While there are many configurations possible, my intentation was to secure the traffic from my iOS device by routing it securely through a Linux server. As such, this HowTo will show you how to set-up an initial working configuration, which you can customize afterward.

Most likely things will be missing, such as how to configure the firewall or the init scripts on your Linux distribution. As it won't be possible to cover all Linux flavors this HowTo will attempt to give you a working WireGuard configuration, leaving it up to you to fill-in the blanks. Feel free to write a comment to touch upon your specific situation to help others that might stumble upon this HowTo :)

Note: In these configuration examples I use 10.8.0.1/24 and 10.8.0.2/24. However, as WireGuard IPs may not overlap your other network interfaces

Poor Man's Global Traffic Manager

Sometimes we need to add redundancy to some service or server which happen to be a public-facing entry point of our infrastructure. For example, imagine we want to add a high availability pair for a load balancer which sits on the edge of network and forwards traffic to alive backend servers.
