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>
