<p class="MsoNormal">I was hoping to get an indication from other providers on how they handle these “blank” authentications hitting their radius servers and whether this is a wide spread problem as it became a huge problem for us.<o:p></o:p></p>

<p class="MsoNormal">Interestingly I’d had a similar issue with 2830 & 130 units doing that with dhcp- despite being in bridge mode they still pickup the dhcp lease from the carrier and prevent the router getting it.<span style="mso-fareast-language:EN-AU"><o:p></o:p></span></p>

<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal">Looking for some shared experience here.<o:p></o:p></p>
<p class="MsoNormal">We’ve had a complaint from our NBN wholesaler that our Draytek’s, which are configured in PPPoE passthrough, are sending blank authentications to their Radius server at a rate which is impacting their services.<o:p></o:p></p>
<p class="MsoNormal">Our standard deployment since about 2010 has been to deploy an xDSL type modem in PPPoE passthrough and then use a router to send the authentication. Interestingly we’ve never had this complaint before…<o:p></o:p></p>
<p class="MsoNormal">Our work around was that our wholesaler requires the credentials to be sent on a vlan so instead of using the Draytek to handle the vlan-ing we changed the router to insert the vlan (so the Draytek can be as noisy as it likes and it doesn’t
affect them)<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I’m wondering if others have also had this experience with these devices… and what you did about it?<o:p></o:p></p>
<p class="MsoNormal">Also, surely if the stupid Draytek is in pppoe passthrough it should know not to try to authenticate itself???<o:p></o:p></p>
