There are
services like
http://www.noip.com/free where you can get a
DNS entry for dynamically changing IP addresses. This way you can
run a BBS without having to buy a business class account.
Yeah... unless I am
behind a NAT - and I believe I am behind at least
two, of which at least one is out of my control, hence no making
holes (or tunnels).
Sure you can tunnel; you just have to initiate the tunnel connection
from the inside. I too have a host (at work)
that's behind double NAT;
it initiates and maintains a tunnel connection to an
external host, and
voila! my external hosts can reach the internal host. Not as good as
native connectivity, but it works "well enough". (Yes, work knows
about it. They don't mind.)
Of course, this needs a friendly host on the outside. In my case, I
find that cost well worth paying....
