Thanks for reply.
That probl= em is resolve.
I am in new difficultly now.=C2=A0

Scenario.
We= have three system say laptop L1, laptop L2 and raspberry pi (say pi).
L= 1 and L2 are connected with wireless interface(wlan0). L1 and pi connected = from ethernet interface via ethernet cable.

Now,
= L1 wlan =C2=A0ip: 192.168.0.9=C2=A0
L1 eth0= ip: 10.42.0.1
L2 wlan ip: 192.168.0.11
pi eth0 ip: 10.42.0.2
L1 wg0 ip: 10.0.0.6
L2 wg0 ip: 10.0.0.2
pi wg0 ip: 10.0.0.3

Now problem is L1 and pi executing ping = command but L1 and L2 don't.

PS: A= pologies for disturbing on weekends. Didn't realize weekend part.=C2=A0=
These are s= ummer holidays here. Each day is same to me.
Some of people like, you, E= ric,Christian Hesse etc. are super experts on certain matters.
My selfis= hness is that I want the quick response to accelerate work.
So approached in this manne= r.

N= ot sure of duplicate part. I think I only send two messages.
One solutio= n to problem and other requesting the tutorial.
Next time I will maintai= n single thread for particular problem.
Please reply whenever feel free.=
=F0=9F=98=8A

Sorry and Thanks again
