A number of virtual hosts are supported on this web server. The host (non-virtual) web content is this single file with a brief note on the addressing.
A long term goal is to transition to an IPv6 only web server but allow IPv4 access to the server via NAT46. The transition steps are:
We are now at step 2. This allows removal of a globally routable IPv4 address from the orleans.occnc.com domain while still running the web server within a FreeBSD jail for security reasons.
Step 3 is a further improvement, a step toward eliminating IPv4 in at least one of the local subnets leaving more hosts IPv6-only. This is going to have to wait until changes to pf to support NAT46 and NAT64 are ported from OpenBSD to a FreeBSD release. It might be that only the af-to support is needed, but af-to works with a different pf code base and af-to alone may not be easy to patch into the FreeBSD pf.
