Can somebody help me. I've turned off my firewall like most of you
said to do and I stll can't send files or use the audio/video on
Windows messenger. I have DSL modem going to a Linksys router to two
computers and it won't work. Running a fresh install of Windows XP.
I have a similar problem, but with some help from Netgear for my router
I have got a bit further.
For me the audio and video worked with the software firewalls turned off
between my XP machines on my side of the router. This doesn't work
between MSN Messenger and Windows Messenger, so both machines must be
running XP to work without installing the separate MSN Messenger.
To work through a router, Windows Messenger has to be able to open and
close all sorts of ports on the router's firewall, and it uses uPnP for
this. So the router has to support uPnP. My Netgear router said on the
box that it did. It came with a slightly old version of firmware, which
I upgraded to the latest version on their site.
At this stage I contacted Netgear, who upgraded me to an even later beta
version of firmware, but this didn't help. Then, on their advice I
completely uninstalled the Norton firewall instead of merely disabling
it. This Norton uninstall has to be done by choosing 'Change' , then
'Uninstall' in the Add remove programs app, not by choosing the direct
'Uninstall', which is a Microsoft function and thus doesn't work.
I also found that one machine had an old dial up connection set up, but
not the default and long since unused, to use ICS. This was removed.
After doing all this and re-booting the machine, one machine will work
through the router. On a second machine to achieve the same thing I had
to re-install the Norton Firewall, which had been installed and
uninstalled previously. Using the Change/uninstall method made the
system come good and it now works using a separate dial-up connection..
The thing that I can't do now is to make more than one machine work
through the firewall, and I don't understand the UPnP portmapping
screens on the Netgear router. I can't seem to find whether the UPnP
should work with multiple machines or just one.
I'm trying to make this work so that the video connection can be used
via the built in Windows component on a wireless laptop.
I hope this is of some help. I'm very impressed with the help given
here by Jonathan Kay. Perhaps he could jump in here and fill in some of
the gaps.
