Did you use Yahoo IM, AIM, or Skype?
Yes, yes, and yes. Works fine.
What about every other service/protocol that users use today,
and might be invented tomorrow ? Do & will they all work with
NAT ?
Some do, some don't. My observation is that in practice the stuff that
people do on consumer DSL works through NAT a lot better than the nanog
conventional wisdom says it does.
Will it stop or hamper the innovation of new services on the
internet ?
Like peer to peer phish bots? I certainly hope so.
R's,
