[Commotion-discuss] Raspberry pi issue (nmap, ping, gateway)

[Dan Staples]

Hi Mikhail,

When you say you used the advanced luci interface on ap1 to solve the problem, what exactly did you do? Was it a firewall issue?

And for internet connectivity on the raspberry pi, what is the output of "traceroute -n 8.8.8.8"?
