            the past couple of weeks we have started seeing issues with
            customers connecting to firewall-authentication-protected
            servers via Telstra 3G. From any other connection you browse
            to the gateway, enter username and password, and the
            firewall temporarily opens the required ports just for the
            IP you connected from. Recently though, from Telstra 3G
            connections, it seems that http traffic to the
            authentication page is sourced from a different IP to FTP,
            SSH etc traffic so the cached authenticated IP doesn’t match
            the traffic’s source IP and is dropped. This has been
            confirmed with several different firewalls and customers.
            Has anyone else seen this or could shed some light on it?<o:p></o:p></span></p>

    Isn't that standard behaviour with any ISP with a (forced) proxy? 
    All HTTP requests come from the proxy IP, all other traffic comes
    from the end user's IP?<br>
