[isalist] Re: For Blocking MSN Messenger File Transfers, TOM Said;

hi Dr.
  i am wondring, why HTTP Filtring not working, while i am adding new 
signatures just as you told below, i even did the packet trace to see whether 
the headers are still same, and those are same, but still my firewall clients 
are able to send/recieve file through MSN Messenger...Now what could be the 
possible cause???????

  Well may be(I Think NOT)... But when you defined those signatures, what was 
your search criteria while adding new signature?
   
  Search in : ?
  HTTP header : ?
  Signature : ?

  Hi EveryOne
  For Blocking MSN Messenger File Transfers, TOM Said;
  All you need to do is configure the HTTP Security Filter with a signature to 
block the following Host Header:
/x-msnmsgrp2p
   
  Now i have Access Rule(Allows Internal to external Only HTTP & HTTPS), while 
adding a new signature, what should be the signature search criteria?
  1.
  Search in : Request headers 
  HTTP header : /x-msnmsgrp2p
  Signature : MSN Messenger
   
  2.Search in : Request URL 
  Signature :  /x-msnmsgrp2p
   
  3.
  Search in : Request headers 
  HTTP header : /x-msnmsgrp2p
  Signature : /x-msnmsgrp2p
   
  I have checked all these combinations of signature search criterias, but NOT 
WORKING!
