Not sure I get all the trickery employed here. /128 doesn’t work? Usually that is point to point to any gateway. It works for gif/gre devices. Otherwise suggesting a /126 in general might be better. |

Quite honestly, I don't get the trickery either. I was following the guide to set up my routing, and ran into the problem that I was using the wrong IP of the /127 and therefore it didn't work. I have just added some text with the pitfalls I fell into myself, to make sure other people don't. The rest of the guide is quite accurate, I just specified some details a little more clearly. |

Slightly elaborated on the use of IPv6 Gateway addresses with respect to Wireguard selective routing.
The documentation mentions the use of a /127 for IPv6, but is not entirely clear on which address to use for the local tunnel configuration and which one to use for the Gateway.
Added a little note on how to use an IP calculator tool to determine which address is which. Mixing up this configuration will make the VPN not work.
