For something very different this time, a quick recipe for a very specific situation.
One of the very few fiber-to-the-home solutions in the UK is through Cityfibre, sold as Vodafone “Gigafast” packages where I live. As with other ISPs they give you their own internet router. If you would like to use your own, here’s how.
TLDR; Obtain PPPoE credentials specific to your account from Vodafone, then use them to configure your router, you need to tag all your packets with VLAN 911.
- Obtain PPPoE credentials from Vodafone. You can do so by using the chat feature on their website. Here’s an example chat transcript pasted here for your enjoyment and pleasure
