Here is my configuration

my PC IP     :192.168.1.57   subnetmask : 255.255.255.0
my device IP :73.83.1.57     subnetmask : 255.255.255.0

i am successfully able to send packet from my pc to device but not able to send packet from device to pc (have checked in wire shark but it show only PC->device packet transmission flow )

Now i have added one more IP like device ip family in PC (73.83.1.60) then successfully able to two way communication.same works in reverse order means i have set my device IP as 192.168.1.58.

So is there any rules like both IP must belongs to same IP family? because sub net mask in both are same. so issue is IP.

Any one have idea? is it correct network behavior? can i solve it without making same IP family.?

Answer 1

If you are using both IPs on the same LAN they should be on the same subnet ex: 11.1.1.1/24 can ping 11.1.1.44/24 but it can't ping 11.1.2.2/24 ( different subnets)

In WAN not necessary, for example 192.168.1.1 can ping 72.1.1.1 ,, but 72.1.1.1 can't ping 192.168.1.1 because this ip is private and when it leaves the LAN it becomes real ip because of NAT (Network Address Translation)
