I have just installed Telstra Australia's BigPond Next-G Wireless Internet which uses the 3G wireless mobile network. The problem is that each time I start-up or reboot I get a totally different IP address for the USB adapter. How can I still use ZoneAlarm Basic to allow access to the internet in these circumstances?

Operating System:Windows Vista Ultimate
Software Version:7.1 (Vista)
Product Name:ZoneAlarm (Free)
