BTW. i have found an error in NetworkManager during hotspot creation. This is the part of the log with the warn:

Feb 06 11:48:53 px30-64 NetworkManager[237]: <info> [1612612133.8279] Executing: /usr/sbin/iptables --table nat --insert POSTROUTING --source 10.42.0.0/255.255.255.0 ! --destination 10.42.0.0/255.255.255.0 --jump MASQUERADE
So i suspect that this line
Feb 06 11:48:53 px30-64 NetworkManager[237]: <info> [1612612133.8062] Executing: /usr/sbin/iptables --table filter --insert FORWARD --destination 10.42.0.0/255.255.255.0 --out-interface
wlan0 --match state --state ESTABLISHED,RELATED --jump ACCEPT
is causing the warning and i think that is why no internet access is being available for devices connected to the hotspot. The question is why?

Hi all,
i have successfully configured hotspot using this command:
nmcli device wifi hotspot password 12345678 ssid softgent
on px30 board which is using realtek wifi (out of tree driver). When i connect to my hotspot from my mobile it all works except that i have no internet access. I can log into this board using ssh from mobile but cannot ping it nor connect to any web.
using command iptables -S shows the output below:
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT
-A INPUT -i wlan0 -p udp -m udp --dport 67 -j ACCEPT
-A INPUT -i wlan0 -p tcp -m tcp --dport 67 -j ACCEPT
-A INPUT -i wlan0 -p udp -m udp --dport 53 -j ACCEPT
-A INPUT -i wlan0 -p tcp -m tcp --dport 53 -j ACCEPT
-A FORWARD -s 10.42.0.0/24 -i wlan0 -j ACCEPT
-A FORWARD -i wlan0 -o wlan0 -j ACCEPT
-A FORWARD -o wlan0 -j REJECT --reject-with icmp-port-unreachable
-A FORWARD -i wlan0 -j REJECT --reject-with icmp-port-unreachable
The hotspot connection has ipv4 method=shared. I also use systemd-resolved and dnsmasq is being run by Network Manager.
Any ideas what can cause this situation?
Thanks in advance for any help.
