The NAT router will create a temporary IP/port combination for the
client, and this combination is what the server will see when
receiving data. The server assumes that this combination will not
change. But this assumption is wrong, especially with UDP as there is
no connection. So the server has to reread the port from the UDP
header everytime it reseives new data from the client and recreate a
socket for it (and clse the existing one of course). That will result
in multiple create/close socket operations per second for every
client. And that will simply result in multiple already in use
errors per second.
You can argue that you've never noticed such NAT behavior, and you are
possibly right. But it will really only work with a so called cone
NAT
router, which will make IP/port combination persistent.
Interesting reading, although not directly connected to this
discussion, is: http://gnunet.org/papers/nat.pdf

Description: A masquerading proxy for flight simulation networks
PCProxy allows multiple flight simulation clients to share a single
network connection to a flight simulation network, such as VATSIM or
IVAO, which is based on the fsd (Flight Simulator Daemon) protocol. This
is particulary useful for players who wish to have multiple network
clients active at the same time. In tech-terms, PCProxy is a
multi-connect masquerading proxy for fsd traffic over TCP/IP.
.
PCProxy currently only supports networks which operate using the fsd
protocol, like VATSIM and IVAO.
