I'm under firewall, I can ping to some hosts but not to other hosts
my IP addresss 172.19.7.111
mask 255.255.240.0
I can ping to host 172.19.2.111
(that I discovered with Angry IP Scanner) but not to 172.19.2.167
which is my rapsberry.
I checked both host IP address with ifconfig
. both have mask 255.255.240.0
