[help wanted] Cant ping from the Emulated to client

[AnduinBrian]

Hello i use FAT to emulate the WR841N device.
After i login, i got shell root. I start iptables to accept the connect:

iptables -F
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT

I can connect to web server from client and the client can ping the emulated router.
But on the router, i cant ping to client (192.168.0.2)

But on the client, i can ping to the emulated router.

I can ping from router to client when i emulated the NetGear D6000. So what actually happend in my case ?

Is there a firewall on the host which is preventing ping?
In case if you already are able to achieve bidirectional communication it shouldn't be an issue.

Also please run ifconfig, brctl within the router and check the interfaces. Maybe there is no route or a misconfigured route which is preventing traffic from reaching the host.

My ufw is off.

There is no bidirectional communication because i cant connect to my tftp sv on the 0.2 client.
The router ifconfig

The client ifconfig

the router brctl

I tried to set the broadcast same as the router but still cant.

Found out, the IP range 192.168.0.1/24 is the problem.
I manualy delete the bridge and create a new one in the router (using brctl). After that i use ifconfig to set ip on both.
It worked.
