<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m looking to talk to anyone who has been receiving large data bills using the APN Telstra.extranet on Telstra’s mobile network. We’ve got a lot of sensor equipment which uses it and over the last 3 months have been receiving large bills
due to what appears to be DoS attacks on the public IP space that Telstra uses.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I suspect we’ll have to move up the level of maturity of technical design to not use public IP (instead have a closed APN).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Some background info I dug up: <a href="http://forums.whirlpool.net.au/archive/2175897">
http://forums.whirlpool.net.au/archive/2175897</a> and Maxon had a link warning customers too (but their site appears to be down today).<o:p></o:p></p>
