IPv6

For some time, I have been covering topics concerning OpenWrt on my website. One of the primary interests among my users has been the implementation of WireGuard and adding a Cloudflare WARP tunnel, as well as managing multiple internet connections on a single router.

What I have not yet covered is how to conditionally route traffic once we have established two internet connections, or when we have added a virtual connection (such as a VPN) to the router on a single physical connection.

While firewall rules can be used to route traffic, they are not always straightforward to implement; consequently, I looked for an alternative solution.

I was particularly interested in being able to quickly configure a router to direct traffic from a specific device over a VPN tunnel whenever necessary. To assist with this, I looked into the PBR (Policy-Based Routing) package.

Cloudflare is known for being the next Google and providing us with high-quality services, many of which can be used for free without any compromises. Fortunately, unlike Google, it is not so eager to kill its services.

From domain management, to SSL certificate for your website, secure and fast DNS, to turbocharging your internet connection with WARP (or WARP+ for those who want more).

The UK’s service providers are very much behind the times when it comes to the latest technological developments. Given the somewhat phlegmatic attitude of the British people towards new technologies, it’s no wonder that ISPs are still stuck in the Stone Age (IPv4), even though the stones (the pool of IPv4 addresses) are gone. While I am lucky to have an external IPv4 address, I can forget about a version 6 address (thumbs down for Virgin Media).

Luckily, there is a solution, and it’s free!

If you have a router with OpenWrt, you have probably thought more than once about how to set up a VPN server on it so that you can connect to the network from outside your home or office and have access to local data, such as a network drive or printer.

You are probably aware that it is very important that the website you visit, especially the one where you enter any data (including login and password) is secured with a so-called green padlock, i.e. served by https:// before the name of the website.
