Alle müssen sich beim Master Server anmelden.
Hier vielleicht noch etwas (habe ich selbst nie probiert):
Zitat von
Sourcforge: nat-traverse:
TECHNIQUE
nat-traverse establishes connections between hosts behind NAT gateways,
without need for reconfiguration of the involved NAT gateways.
1. Firstly, nat-traverse on host "left" sends garbage UDP packets to
the NAT gateway of "right". These packets are, of course, discarded
by the firewall.
2. Then "right"'s nat-traverse sends garbage UDP packets to the NAT
gateway of "left". These packets are *not* discarded, as "left"'s
NAT gateway thinks these packets are replies to the packets sent in
step 1!
3. "left"'s nat-traverse continues to send garbage packets to "right"'s
NAT gateway. These packets are now not dropped either, as the NAT
gateway thinks the packets are replies to the packets sent in step
2.
4. Finally, both hosts send an acknowledgement packet to signal
readiness. When these packets are received, the connection is
established and nat-traverse can either relay STDIN to the socket or
execute a program.
Edit: Wobei ich hier nicht verstehe: Was ist wenn "left NAT-Gateway" den Port ändert?
