Question About DMZ jim evans 10-21-2005

I can't get MSN Messenger to permit application sharing. I use a
LinkSys router. Several people have suggested I need to forward
certain ports, but each person lists different ports to forward.

As a test, I pointed DMZ on my router at my machine. As I understand
it, DMS opens/forwards all ports. So, that should rule out any port
forwarding issue, is that correct?

Jim, as I understand it yes. The router should forward to your pc in the DMZ
all traffic that it does not otherwise have a rule for. This does mean that
if you (say) had a rule to forward port 80 (http) to some other pc then your
pc in the DMZ wouldn't be forwarded traffic on that port. So if you do want
to do a test then make sure you don't have any rules that might be
forwarding on the ports you require.

Hope this helps.
