I have an ap in banana pi whose ip is 192.168.4.1.

And eth0 on banana pi whose static ip is 192.168.144.100.

 

I would like to connect device A from banana pi's ap and also it can ping to the eth0.

 

So far I had tried:

sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

sudo iptables -A FORWARD -i wlan0 -o eth0 -m state --state RELATED,ESTABLISHED -j ACCEPT

sudo iptables -A FORWARD -i eth0 -o wlan0 -j ACCEPT

 

 

Might also need this:

echo 1 > /proc/sys/net/ipv4/ip_forward
