<p class="MsoNormal">Good morning,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-GB">i would like to ask how to configure dnsmasq (DHCP options) to tell the client not to use this network for accessing Internet.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">My server is listening on bluetooth interface; mobile phone connects to the server and establishes networking over bluetooth. Server is serving DHCP to assign the mobile phone address for communicating with the server.
This networking-over-bluetooth connection shall be only used for communication between those two. The server is offline anyway.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">My problem is, that once the mobile phone connects to my server, it sometimes attempts to use the bluetooth connection to access Internet, instead of using mobile networks (4G). Often web browsers fail to show webpages
(DNS probe no internet).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I tried to fix this issue with following parameters to dnsmasq:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">--dhcp-option=3 --dhcp-option=6 --dhcp-option=33,<serverIP>,<serverIP> --dhcp-option-force=121, <serverIP>/24, <serverIP><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">However it does not really help.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">The problem is complicated, because it must work for "all" types of mobile phones (Android and iPhone) and they are difficult to debug.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Thanks much for any advices!<o:p></o:p></span></p>
