On my current internet connection at home, I do not have direct access to an external IPv4 IP address from my router (only IPv6 is available). Because of this, I am unable to set up my VPN server using WireGuard directly. Therefore, I need to support myself with Cloudflare Zero Trust technology.
Following my guide on how to add a Cloudflare Tunnel to an OpenWrt Router, as a WireGuard VPN alternative, I managed to regain access to my network from outside my home.
There is, however, one issue with this solution.
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.
