Re: Stopping MSN Messenger Service on PIX

There's a wealth of this information on the Internet, just plug "firewall block msn messenger" into Google and you'll get tons of hits.

Some stuff I came up with is:

Blocking MSN Messenger is pretty easy, and if you look at my other blocks for this, you will notice that I do a port block and a IP range block. This isn't really needed, but since this can be done, I do. Here are the things you should block to kill MSN Messenger:

· TCP Port 1863

· IP Range

So on the PIX that would equate to:

> access-list outbound deny tcp any any eq 1863

> access-list outbound deny ip any

> access-list outbound permit ip any any

> access-group outbound in interface inside

Haven't actually tested it myself, but as I said, there's a bunch of information about doing this available in any search engine.

Thanks for the input, I knew it was port 1863 but could not remember the IP range, as I was on a customer site. And I know were you got that info from too..

But thanks for your time.
