perfect solution for remote access without a IPv4 adress

Guys,
hallo.. I am Hanno, DK3HV in Germany. Here in Europe we are suffering from missing IPv4 address. Most new installations will not give a IPv4 address and instead a IPv6. In such case all the nice solutions provided by Flex does not work because you need a stable and known IPv4 address.
But clever guys found a solution. Mike, DM5XX of the D4C team developed a fantastic solution, very specially focused on the remote access with FlexRadio. I use the solution now two times: one to reach my home (8400+PGCL+TGXL) and one to reach our club remote station DF0KK/R (6400 ATU).
It works perfect with the VPN solution to get the Software running from any remote laptop PLUS connecting the Maestro to the remote.
Since yesterday it out of the experimental phase and they offer the solution to the public.

I posted it yesterday to the FlexRadio Facebook group, but was informed I should do here in the community. I deleted the Facebook because I was informed that it is no problem in the USA. I was not aware that the Facebook group is dedicated to the US users of Flex.
