[arm-allstar] Setting up node on Cellular connection

[Benjamin Naber]

Gents,

A VPN may add un-desirable latency from the crypto.

If it works to satisfaction, then ignore this message.

Just as there are folks on IPv4-only (my ISP is only IPv4), using IPIP
6to4 tunnels to get IPv6 connectivity, you can do the same for IPv6 to
IPv4. You will most likely need to make sure the MTU for the tunnel is
1480.

Find the guides for setting up the IPv6 tunnels, and do the opposite.
In this case, you'll be able to use just about any hosted server whom
has a dual-stack IP connection.

You *may* have to get creative with the 'routes' on the endpoint tunnel
router though, you may have to specify a ip -4 route  with a very low
metric to ensure packets going out IPv4 and not 6.

An alternative, perhaps better, on the endpoint tunnel router, ensure
resolv.conf contains ONLY a IPv4 address for DNS queries.

If this stuff is above your head, get learning. This Internet/computer
stuff is going to keep 'evolving' as time goes on. It not beautifully
simple as AM or FM!
