Blocking access to MSN Messenger 7.0(Beta)

Hi,

Can anyone help? I'm tearing my hair out trying to restrict my childrens use of MSN Messenger 7.0(Beta). I have tried any number of solutions I have found on the Web but none work. I am running under XP Pro and have a Netgear DG834G Firewall which controls access from all 3 of our computers to the Net. The children come in via a Wireless connection to the Firewall.

Your hopefully,

Jeremy Britton

Yep, Tried the things in this thread too, but no real help I'm afraid. Anyone else offer any helpful suggestions? MSN Messenger 7.0 seems to have lots of alternative TCP ports and i/p addresses that it tries; I have even run a network traffic analyser product called Ethereal which throws up lists of TCP ports and i/p's that MSN seems to be using - as fast as I block some, other appear. Someone out there must have a clue how this product works and what the definitive way to block it is........

try editing the hosts file.

its in c:\windows\system32\drivers\ect

put entries in there for

127.0.0.1     gateway.messenger.hotmail.com
127.0.0.1     messenger.hotmail.com

this should stop them from being able to login. Unless there are other login servers I don't know about.

Thanks for that - what I really want to do is to restrict access rather than block it altogether (which I can do with my firewall now) however. Its the ports it uses I need to know; I can't find anything anywhere on the 'net that tells me what they are, hence my posting here. Jeremy
The way they make these chat programs now it's almost imposible to block ports. If they cant get through on one port they scan for any open ports and try to use them.

A couple of links that may help some; the first of which details blocking MSN Messenger in corporate environment, but may add insight and shows ports...  the second has helpful links about security related issues and the beta item you've mentioned.

I've been looking into the MSN Spaces beta and found it interesting and curious if it may provide some workarounds...
MSN Spaces Offers Protection and Control

MSN Spaces is designed to give consumers control over how they share their Space information and who can access it:

Permissions. Consumers have three permission control settings on their MSN Spaces site, enabling them to decide just how widely they want to share their content:
Public: Viewable by anyone
Contacts Only: Viewable only by their MSN Messenger contacts
Private: Viewable only by contacts whose e-mail addresses are manually entered by the MSN Spaces author or selected from an MSN Contact list
Controls. MSN Spaces gives the consumer control over how others interact with his or her Space. MSN Spaces includes settings that give each person power over who views his or her Space and how people can interact, read and comment on the Space. This includes the ability to set up the Space so people can read but not comment.
Statistics. Consumers will be able to track visitor statistics on their Spaces site, so they will know how many people are visiting as well as other detailed information.
Here for more, if this interests you.

If I've missed the boat and misunderstood, apologies.

I have exactly the same router at home.
The schedule function doesn't work, so you cannot allow or block by schedule, and also, I've blocked all TCP/1863 and access to 207.45.1.1-207.46.254.254 (or whatever the IP addresses are in the below article, which I can't see for some reason...), as you would do on a corporate firewall to block MSN, but still, it gets through.

I think there's something wrong with the Netgear software !
If anyone finds a way to do it with the Netgear, then let me know - I can do this with PIX, CheckPoint etc, but the darn Netgear just does not play ball !!  :)
Tim, My Netgear router works fine - the schedule thing blocks everything within the times I state and I really value the product. The issue is with MSN Messenger and it looks impossible to block to me - it just keeps finding a way round. Nice one Microsoft.... I'm a bit disappointed the brains on this forum don't have an answer though - time to look somewhere else I suppose.
As is the case always, "beta" means just that and doesn't even have 'developer support' for obvious reasons (beta out to test and collect user information) ....  so although I sure hope you find a solutions, would venture to say that participating in the MSN Messenger Beta process and forums may be your most direct route to escalate issues and have the developers help resolve issues.   Since I rarely run 'beta code' these days (having done it for years in the efforts to help resolve 'final release' issues), must admit this isn't one of the ones I've tried.  I sure hope you find what you seek, and would definitely consider (were I in your shoes) to participate with the MSN related user groups and forums within the MSN environment to escalate your issues and seek developer assistance.

I can get my Netgear to completely block MSN access by disabling port 1863 and blocking access to the 207.x.x.x MSN servers, as explained in my post above.  Does this not work for you ?
Trouble is, I cannot do this by schedule.  Both Allow By or Block By Schedule tactics have the same non-affect ! :)
Tim, Thanks for that, so can I. My point is that I am trying to use the Netgear firewall controls to schedule access to MSN rather than block it completely. I am trying to teach my children to use it responsibly but I need a back stop! It seems to me there is a bug in the Netgear firewall, which your post rather confirms. Thanks for the input. if you can throw any more light on the problem all thoughts welcome. I tried contacting Netgear but no joy there.

There are some severe problems with Netgear's firewall module!
I managed to block access to MSN Messenger by adding a static route for 207.46.0.0 255.255.0.0 and pointing it to 127.0.0.1 (which blackholes the traffic).  This can be done via the Netgear web interface.
Works a treat....   but strewth, the Netgear firewall is a joke - maybe it needs rebooting each time a new policy is applied ?  Who knows... ?  ;)
Tim, Thats really helpful. Can you explain to me how I set up that static route? I'm a bit of a novice on this firewall stuff! Which web page do I use and how do I set it up please? I feel I'm on the verge of getting the answer I need......
When you open up the Netgear web page, there's an option on the left hand side saying 'Static Routes'.  
Go into this, and click Add.

Name - can be anything - say MSN
Tick the Active checkbox
Destination IP address - 207.46.0.0
IP Subnet Mask - 255.255.0.0
Gateway IP Address - 127.0.0.1
Metric - 2

Apply

Should do the trick.. :)
