Windows Messenger behind Firewalls and Routers

bjrugg

I am trying to set up video and voice on Messenger 4.7 for my wife to use
with a friend in the Netherlands. The Holland friend has a Dell wireless g
router connected to local DSL and has recently purchased several Dell
laptops with Windows XP Home running Norton Firewall.
I have a Netgear 614 (UPNP on) wireless router with cable modem and a wired
Athlon 1700 (UPNP Loaded)running a Kerio firewall.

The chat works fine, but I want to use the webcam (Intel cs110) to do video
and voice.
Does your following article apply or is this task mission impossible (
Punching holes in the firewall as noted in the article? Do you need UPNP on
with both machines?)

Hey

That must be old. My wireless router support UPnP. Hasn't solved my problem. See my other thread below. My XP home has UPnP on, router has it on, target has it on. No luck

oh

I've been frequenting this newsgroup for ages with a particular similar
problem, which now I appear to have sorted.

My answer would be - Yes you need UPnP on the routers at both ends.
But... I could never get a Netgear DG-834 router to UPnP properly even
after 3 months with support and being escalated to the highest level. It
worked with one machine but with no others of mine.

A D-Link DSLG-604T router did work with all machines but was unstable.
The first firmware upgrade released about a week ago appears to have
made it much more stable and it now seems to be working fine with UPnP.
However, I did have some weird effects with a couple of cheap pcmcia
wi-fi cards, Binatone WL1000's. These worked fine until I fired up any
other wi-fi kit in the area, and then they would go into a
connect/disconnect rhythm at about once per second. A call to support
revealed that the firmware on the support website was out of date and
that there was a hidden ftp site which had a much later version.
Upgrading to this cured these problems.

It is possible that the card problems might have been related to the
Netgear problems, but I returned the latter, so now I'll never know.

It seems to me that all this stuff is being sold before it is reasonably
well debugged, and it is incredibly difficult to get any solid
information about testing methods and so on.

I started this because my son asked me to set up my little network to
exchange video and audio with a view to then researching the security
dangers relating to UPnP, and then trying to manage them.

It has been embarrassing in the extreme that I haven't been able to even
begin to look at the security aspects because I couldn't get the basic
Windows XP Messenger to work.

This may not be the place to say this, but I am also quite disgusted
that Microsoft can sell IBM a non-transferable licence tied to a
particular machine, and include, as part of the OS, XP Messenger which
both Microsoft ("it's the OEM provider's responsibility") and IBM ("It's
a usability feature not covered by the support contract") will not
support.

My advice would be to be very wary of opening all those ports as in the
Jonathan Kay article. It didn't work here with the hardware that I had
at the time. Jonathan does a wonderful job in this newsgroup, but he
does seem to be fighting a rather immature technology.

I can get the voice working with Yahoo Messenger, but the video hangs every
time.
When ever I try to do the Web cam thing on Yahoo IM, the system hangs and I
have to restart XP Pro
I can get NetMeeting to see the camera webcam, but I have to select it as
the ATI is first in the dropdown list of devices.
This computer has an ATI video ALL-In-Wonder card (7500) that can do
video-in via camcorder and TV and video out also.
It looks like the Yahoo Messenger is hanging on the device and pointing to
the card as opposed to the camera.
I will try the camera on another computer and see what happens.

I've had trouble like this, as to do any meaningful local tests I had to
run at least 3 machines all with webcams and audio set up.

Although I've used Yahoo Messenger in the past, I know very little about
it. My 'understanding' is that the Yahoo app uses fixed pre-defined
ports for the communication and so is less or not at all reliant on
UPnP.

Yahoo Messenger and XP Messenger are almost certainly incompatible. Am I
right to think that the video in YM has to go through Yahoo's servers?
The video in XP Messenger, when it works, is routed directly peer to
peer under the direction of the Microsoft servers. This ought to be much
more efficient, but it does mean that any firewalls have to be aware
that the Microsoft app might open any one of a huge number of ports.

What I would like to find is a clear explanation somewhere (in simple
terms for a simpleton like me) of where the decision is made about which
ports to open for the video in XP Messenger. .

The webcam installed fine on a laptop and same webcam worked with yahoo im.
I went back to the desktop with the webcam and the webcam hangs when I do a
webcam compatibility test at
http://help.yahoo.com/help/us/mesg/webcams/index.html
Running this web page in another IE instance gives me an error saying
'ywcupl.dll' is already running and will not go any further.
Will try a few more things later on the desktop - a conflict somewhere
