This document is *PRE PRODUCTION*.
h2. Introduction
To enable IPv6 only VMs to be accessible from the IPv4 Internet, we have an IPv4-to-IPv6 proxy.
h2. How to use it (as a customer)
* 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
h2. Technical details / how to maintain it
* It's configured by cdist, type @__ungleich_haproxy@
* To add a domain, edit manifest/ungleich
** Find ipv6-proxy.ungleich.ch
** Verify that the domain has an AAAA entry
** Add the domain using the "--v4proxy DOMAIN" parameter
** Commit in git, push
* Run cdist: @cdist config ipv6-proxy.ungleich.ch@
h2. Troubleshooting
If the customer domain does not exist (anymore), haproxy will refuse to reload. In this case the customer domain has to be removed and the customer to be notified.
