@Akshay: Thanks for the offer! I'm looking more for a place to tinker
and do development, so it definitely wouldn't be safe to play on your
production machine.
@Brad: I've never looked into UML, but it looks very interesting.
@cGull: Setting up a NAT on my own hardware sounds good. At the very
least I'm sure the exercise will be educational. I would be inclined
to do it using virtual machines on just one PC.
The whole reason I've run into this NAT business is because I want
real peer-to-peer connections (without relaying data through a central
server), in order to reduce latency for streaming (real-time) data.
To cover all the bases, I must be able to connect all combinations of
PCs behind different NATs, the same NAT, or no NAT at all. That way
anybody can connect to anybody else (with a few exceptions).
If I can figure out how to initiate peer-to-peer connections through
various network setups, I'll still need to experiment with latency and
packet loss over the "real" Internet. But I'm just getting started,
so this is a way off.
I have enough to keep me busy on my own hardware for a while - I'm
just trying to map out a general direction. I'll get to work on
setting up some virtual machines.
