Over the past couple of years, I’ve been quite accustomed to my ISP providing me with an IP block (typically a /29) instead of just a single static IP, but recently I’ve switched to Hyperoptic for their FTTP offering (Because, Gigabit!). Unfortunately, they seem to only offer single IPs for residential service and require you to be on their business package which costs £££ if you want more IPs.

To get around this I decided to try to tunnel some IPs home – My setup is rather complex but I’m going to skip over the specifics for most of it and focus on the issue I was facing – lets ignore how the IPs route around the rest of my network and ultimately end up at the router for now and just look at the rather simplified view below.
