RE: [GD-General] Sockets question

[Nicolas R. <nic...@fr...>]

Hi,

I think UDP always need a port, whether you bind it (define the port) or
not (port is choosen by the socket stack at runtime).
It means that since you are listening on a given port, if you use
another socket to respond, it will be on another port. Which is likely
to break NAT/PAT networks anyway.
Apart from that port-translation thing (and of course
filtering/firewalls), I don't see why it wouldn't work.

Note that if you are using the personal firewall (XP, 2000 ?) you may
have a rule which forbids UDP reception from a source you never sent
anything to before (which is the case if you change sockets).

Merry Xmas anyway !


Nicolas.
