DS-Lite: a solution By Michiel van der Vlist (2:280/5555)
Earlier this year, in May, Fidonews 34:20 I reported about my first DS-Lite emulation experiment. Among other things I wrote this:
There was one thing that was a bit problematic though. When I am on the move, I run a point system on my laptop to keep in touch with Fdionet. This won't work when I am on an IPv4 only network since I can not connect with my IPv6 Boss Node from there. Most public WiFi networks on campings and hotels are still IPv4 only. So are nearly all 3G/4G mobile operators in Europe I am afraid.
I also wrote that to my surprise I found that Teredo was still operational and that it was just good enough at times for an IPv6 binkp connect. But just barely.
Feste-IP offers several IPv6 related services like DDNS, VPN and HTTP proxy, but the part that got my attention was the Universal portmapper. All that is needed is that you create an account and fill in the host name or IPv6 address and port number of the server that is running on your DS-Lite connection. What you get in return is a host name that points to a dynamic IPv4 address and a port number. Well, they say it is a dynamic IPv4 address, but I have not seen it change yet. Whatever, yur IPv6 server is now connectable from an IPv4 only client via that host name or IPv4 address and port number.
My IPv6 binkd server is now available at de8.portmap64.net:24554
In my case the port number for the IPv4 side is the same as the one for the IPv6 server, but that is because I seem to be the only one that asked for port 24554. If I specify port 80 for the IPv6 target, I am assigned port 45990 for the IPv4 side. This way they can use the same IPv4 address for many users.
There is more than one way that leads to Rome. Some will argue that this portmapping server has limitations and that running a fully fledged VPN tunnel is "better". To each his own. I find this service convenient if one needs just one or a few ports. No need to install anything on either the server or the client. And it is cheap. Just EUR 5/year per port and the first 50 days are free.
To test if this portmapper thing is useful for Fidonet I had the A record of fido.vlist.eu point to the IPv4 address of the point mapper service and had my binkp server answer on IPv6 only, thereby effectively simulating a DS-Lite connection for binkp. If you have connected to my Fidonet system between Friday Aug 11 20:00 UTC and Sunday 13 Aug 20:00 UTC, you have connected to my IPv6 only binkd via the feste-ip.net port mapper. My guess is that no one noticed.
There is just one drawback. I have no problem with it but some may have. The web site of feste-ip.net is in German. Can't have it all.
