A very strange situation is:
With previos mentioned / listed configuration from network 1 192.168.0.0/24 actually it possible to ping either ZSHLL 2 and, inside the network 2, 192.168.2.3 but not the other ones !!!!
This is a NAS disk equal to an other present at 192.168.2.2 but this is not pingable or browsable.
Thank for anu suggestion or help.
PS from site 2 no address are pingable,
