No, the main problem is that A is behind my ISP's NAT. I want to access it
from C (yes, I'll be travelling a lot and C might be just about anywhere).
But the problem is that since A is behind a NAT, the connection must be
initiated from A's side to C. Also, since C might be behind some other NAT,
the connection must be initiated from C's side to A. This simply cannot work
simultaneously, so I tried to make use of my public server B which can be
used as a "bridge" between A and C. So, A connects to B, C connects to B, and
then A and C communicate. Roughly speaking...
That was my initial idea, but seems too complicated to work out, so I asked
for a possible easier alternative. :-)

That would be the most obvious solution, if only the ISP were willing to give
me a static IP. But they are not. :-(

Hmmm... This is interesting. I'll look up to www.no-ip.com, but I think that
such dns trick may work only with public IP numbers. And A's IP is of type
10.0.*.* which is a no-go, afaik.
However, I might ask the ISP to provide me with a public IP. It could still be
dynamic, but public rather than local, and in that case the trick with the
dns just might work... ;-)
Thanks for the pointer!
