Can you please be more specific? You mean this happens when you are
connecting from inside intranet to some other point inside intranet?
I don't understand your topology. Intranet should have the same class
network, C-class for instance /24, and the gateway should not see the
packages from between 2 hosts in the same LAN. The switch/hub would see
Can you please be more explicit of what's your setup, gateway rules,
firewall, and what you are trying to do?
PS: if you are connecting from outside to inside, through the gateway
which does nat, this sounds like bad firewall/nat rules.
