Hi,
with the ESP in AP mode, it acts as a DHCP server.
when doing that, it han… ds out IP addresses to any client and also it tells them network information like the DNS servers and gateways.
And thats exactly my problem. When a DHCP server hands out DNS server and default route-adresses, a mobile device like my android smartphone will try to use the ESP8266 as a router to get to the internet -- which will of course fail.
This could be prevented by not sending the DHCP options 3 and 6.

Is there anyway to disable or configure the DHCP payload which is sent by the ESP?
Thanks,
Tobias
