I don=B4t know any details about how MSN Talking works but I guess that =
it is
like all other similar programs. If this is the case the application =
chooses
random ports for the voice-traffic (within a limited scope). This means =
that
you either have to open up your firewall for all these ports (that =
means a
BIG hole through the firewall) or use a firewall that understands the
signalling and can open upp the specified ports for a short duration. =
The
last option is of course the best way to go about it but as far as I =
know
this kind of software does not exist yet. This is a big problem for all
Voice over IP right now but hopefully this will be solved soon. Correct =
me
if I=B4m wrong.
