Re: Stop chat programs on PIX-506E

Hi -

To stop MSN you'll need to block the following:

TCP Port 1863

IP Range 64.4.13.0/24

So on the PIX that would equate to:

> access-list outbound deny tcp any any eq 1863

> access-list outbound deny ip any 64.4.13.0 255.255.255.0

> access-list outbound permit ip any any

> access-group outbound in interface inside

I have actually implemented this on a customer PIX 515 (6.2.1) and it works fine.

Hope this helps, also, for the other services check this URL and click on the relevant service, ICQ,AOL etc.. http://testweb.oofle.com/messaging/index.htm

Thanks - Jay
