How to proxy from IPv4 to IPv6 in an IPv6 only kubernetes cluster.

|
||||
## The crazy project: IPv6 based IPv4 proxies in Kubernetes
|
||||
|
||||
If you know ungleich, you know that we always push the limits of what
|
||||
is possible. Today we want to push the barrier of "where can
|
||||
IPv4-to-IPv6 proxies live" a bit further. Let's see how that is going
|
||||
to look like!
|
||||
|
||||
## IPv4-to-IPv6 proxies in general
|
||||
|
||||
Before going into the details, let's see how and why we use
|
||||
IPv4-to-IPv6 proxies in general:
|
||||
|
||||
|
||||
|
||||
The basic idea is that IPv6 only services are made reachable via
|
||||
IPv4-to-IPv6 proxies towards the IPv4 world. So far we are offering
|
||||
this based on standard virtual machines. You can checkout
|
||||
[our previous tech
|
||||
talk](/u/blog/ungleich-tech-talk-2-accessing-ipv4-only-devices-via-ipv6/)
|
||||
for details on how this works.
|
||||
|
||||
Let's try to dial things up a few notches, shall we?
|
||||
|
||||
## Moving the IPv4-to-IPv6 proxy into kubernetes
|
||||
|
||||
You are probably aware that at ungleich we are moving our workload
|
||||
from [cdist](https://cdi.st) + virtual machine automated workloads
|
||||
towards Kubernetes. At ungleich we are using
|
||||
[haproxy](http://www.haproxy.org/) as a basis for our IPv4-to-IPv6
|
||||
proxies. Moving this into kubernetes
|
||||
|
||||
|
||||
|
||||
## Other solution?
|
||||
|
||||
As you can see, mixing the dynamic IP generation and coupling it with
|
||||
static DNS entries for IPv4 resolution is not the easiest tasks. If
|
||||
you have a smart idea on how to solve this without manually creating
|
||||
entries for each and every service,
|
||||
[give us a shout!](/u/contact)

### The prettysocks SOCKS5 proxy (update 2021-11-24)
|
||||
|
||||
On 2021-11-23 we have been notified that there is a new workaround
|
||||
available:
|
||||
[prettysock](https://github.com/twisteroidambassador/prettysocks/tree/ipv6-literal)
|
||||
is a Socks5 proxy written in python that allows the use of Microsoft's
|
||||
**ipv6-literal.net** domain, but from any OS or browser, which is
|
||||
pointed to the proxy. So to access **fe80::1ff:fe23:4567:890a%3**,
|
||||
configure your browser to use the local prettysocks Socks5 proxy,
|
||||
replace the link local address with
|
||||
**fe80--1ff-fe23-4567-890as3.ipv6-literal.net** and there you go.
|
||||
|
||||
There are two interesting things to say about this solution:
|
||||
|
||||
* It is a very simple solution
|
||||
* It is surprising that browser vendors haven't implement such a
|
||||
simple solution themselves so far - does it need an RFC that defines
|
||||
the domain to be used?

||||

||||

On order, you get access to an server without operating system
|
||||
or booted into Alpine Linux via USB stick.
|
||||
|
||||
You have remote access (keyboard/mouse/video) via IPMIview (access
|
||||
protected using Wireguard VPN), which allows you to install an
|
||||

|
||||
|
||||
It has power efficient Intel Xeon L5640 CPUs running at 2.27GHz.

|
||||
can be added for 75 CHF/month. The server is located in an *IPv6 only*
|
||||
network. It can reach the IPv4 Internet via outgoing NAT64. If you
|
||||
need **incoming** IPv4 connectivity, we offer dedicated public IPv4
|
||||
addresses for 9 CHF/month. They are mapped via NAT64-SIIT
|
||||
to an IPv6 address of your choice.

||||
|
||||
You can host your photos and data (f.i. via Nextcloud), run a
|
||||
community chat (f.i. via Matrix) or host your company website
|
||||
(f.i. via wordpress) on it.
|
||||
|
||||
Or you can deploy your own cluster of virtual machines - maybe even
|
||||
IPv6 only Kubernetes on top of it?
|
||||
|
||||
## What if it hardware breaks?
|
||||
|
||||
As this is real hardware, hardware failures can occur and they will be
|
||||
repaired without any extra cost. It is however your responsibility to
