# NFTables kube-proxy

This is an implementation of service proxying via the nftables API of
the kernel netfilter subsystem.

## General theory of netfilter

Packet flow through netfilter looks something like:

```text
             +================+      +=====================+
             | hostNetwork IP |      | hostNetwork process |
             +================+      +=====================+
                         ^                |
