With heightening concern regarding the state of internet privacy (fuelled in part by the passing of the Investigatory Powers Act in the UK), I have set up a VPN server on the virtual server I have hosted with Mythic Beasts. This uses strongSwan and certificate-based IKEv2 authentication.
Assumptions:
debian.example.com
, a public IPv4 of 203.0.113.1
and a public IPv6 of 2001:db8::1

For automated deployment of a similar setup, albeit Ubuntu-based and using ansible for deployment, I recommend you take a look at Algo VPN. I used that project as a basis for my configuration.
The following are examples of the four types rate limiters discussed in the accompanying blog post. In the examples below I've used pseudocode-like Ruby, so if you're unfamiliar with Ruby you should be able to easily translate this approach to other languages. Complete examples in Ruby are also provided later in this gist.
In most cases you'll want all these examples to be classes, but I've used simple functions here to keep the code samples brief.
This uses a basic token bucket algorithm and relies on the fact that Redis scripts execute atomically. No other operations can run between fetching the count and writing the new count.
