## Current Setup
Currently I am renting a VPS which runs a custom proxy, that loads the configuration from consul based on tags and then accepts traffic on the proper ports and forwards it manually.

## Plan
Services that need to be exposed get their own virtual IPv6 address using keepalived. The active/master node will be forced to the node on which the service is currently running using priorities.

On my external server setup Jool with SIIT-DC and iptable rules.
1. Everything coming in at the given port for the service (for example HTTP, Teamspeak, etc.) is redirected to a different internal IPv4 address using iptables
2. Jool listens on the internal IPv4 address and performs SIIT-DC or SIIT-EAM forwarding to the correct virtual IPv6 address
