I have 3 insides :

Inside-01 : 172.16.1.0/24

Inside-02 : 172.16.2.0/24

Inside-03 : 172.16.3.0/24

From Inside-03, i can ping all range in Inside-01

From Inside-02, i can ping all range in Inside-01 except one ip(172.16.1.121)

i disable all firewall in windows(172.16.1.121)

i think the ftd stuck in this ip=172.16.1.121

172.16.1.121

what device is this IP, Looks for Local FW issue as per the description, check device has any FW build in (most Windows and Linux have buit in FW).

if the FW disabled on device, is the profiled from any central ?

from device can you able to ping outside ?

I suggest turning off any antivirus on the host machine. Some AVs also provide firewalling.

It was so stupid issues. I just turn off the network adapter and enable again and the ping was fine !

Thanks guys for your answers and support
