This document is *IN PRODUCTION*.

h2. Introduction

To enable IPv6 only VMs to be accessible from the IPv4 Internet, we have an IPv4-to-IPv6 proxy.

h2. HTTP(s) proxying

* Configure / setup your website to be reachable by IPv6

* Ensure that your domain name has an AAAA entry pointing to your website

* Inform the ungleich team via support -at- ungleich.ch about your domain

* Our team will setup the proxy to whitelist your domain

* Setup an A entry for your domain(s) pointing to 

** 185.203.112.54 (if your VM has the IPv6 address in the range 2a0a:e5c0::/48)

** 185.203.115.0 (if your VM has the IPv6 address in the range 2a0a:e5c0:2::/48)

h2. SMTP proxying (experimental)

This service allows you to *receive* emails from the IPv4-world on an IPv6-only node.

* Configure / setup your mail server to be reachable by IPv6, with a proper MX record.

* Inform the ungleich team via support -at- ungleich.ch about your domain.

* Our team configure the proxy for your domain and come back to you.

* Add a *second* MX DNS record pointing to @ipv6-mx.ungleich.ch@, with lower priority (= higher priority number) than the original one (e.g. @domain.tld IN MX 20 ipv6-mx.ungleich.ch.@).
