Why are packets not going to the Raspberry Pi AP?

Question

linux

Greetings. Did everything according to the instructions . In general, everything works, DHCP addresses are assigned to clients, but not a single host is pinged, both from the raspberry side and from the client side.

Answer 1

All due to my carelessness. Wrong number in /etc/dnsmasq.conf
Configured access point

Answer 2

I would also like to know what exactly you did according to the instructions, an access point, a media server, an sdr receiver, or something else that is described in that review article.
give more information, what did you do, what happened.. show logs

Answer 3

You should at least write messages to the ping program. It also makes sense to run traceriute.
