If you follow my website and posts related to OpenWrt you have probably come across my post about installing a VPN server on an OpenWrt router using WireGuard.
WireGuard is one of the fastest protocols available for creating a VPN connection. Thanks to it, from the Internet, we can easily connect to our network and use it, either for local purposes (access to a printer or network drive) or to limit regional restrictions. Being outside the country, I can connect to my router at any time and my device will appear on the Internet as if it were where the router is, i.e. in the UK.
This super fast solution, however, requires configuration, which can sometimes be complex and cause various errors (although it is usually much easier than other VPNs).
WireGuard also has a limitation. To connect to our router, we need an external (static or dynamic, it doesn’t matter) IP address.
