I  have configured an ISA rule to block MSN Messenger (and Live Messenger) from our network.

It works fine but there appears to be an issue with it also blocking iPhones connecting to the internet via our internal WiFi network (via Safari).

My rule looks like this - if something is not mentioned it is because it is unticked or greyed out.

General :

Maximum headers length (bytes) : 32768
Allow any Payload length

Methods:

Allow all methods

Extensions :

Allow all extensions

Headers :

Server Header - Send original header
Via Header - Send default header

Signatures

MSN :
Search in request headers
HTTP Header : User-Agent:
Pattern MSN Messenger

Live
Search in request headers
HTTP Header : User-Agent:
Pattern: Windows Live Messenger


Properties

Name : Block MSN over HTTP/HTTPS

Action
Allow
Log requests matching this rule

Protocols
Applies to selected protocols
HTTP
HTTPS

From  
Internal (No exceptions)

To
External (No exceptions)

Users

Applies to : All users
Exceptions : FWA (short for full Web Access)

Schedule
Always

Content Type : All Content Types.

However, when a user attempts to connect to the internet wirelessly, for example by iPhone the connection attempt gets blocked at the firewall with the following message :


Denied Connection SERVER 13/10/2010 14:03:55
Log type: Firewall service
Status:  
Rule: Block MSN over HTTP/HTTPS
Source: Internal ( 192.168.1.30:52568)
Destination: External (bbc-vip015.cwwtf.bbc.co.uk 212.58.246.94:80)
Protocol: HTTP
User:  
Additional information
Number of bytes sent: 0 Number of bytes received: 0
Processing time: 0ms Original Client IP: 0.0.0.0
Client agent:

I just can't figure out why it is blocking that connection - can anyone help please?
