Hey folks;

Easy big fella << that one is for you Tom ;-)

Here's my 2c...

Ratko, your packets are failing because of a 'norfc1918' option on the eth0
interface in your '/etc/shorewall/interface' file. (I suspect)

Now the question is why? norfc1918 is used to drop packets that should never
contain rfc1918 network src addrs. (Like from the internet?). If you are NAT
with some other device (DSL modem, firewall, etc) and your eth interface is
using one of these addresses (10.x.x.x, 172-16-32.x.x, 192.168.x.x) then you
need to remove it from that interface.

BTW those 'attacks' look like some drones (spyware, adware, etc) running on
your workstations that are trying to connect to your default gateways' web

But Again,  Tom always suggests that you show us your files (see
shorewall.net/support.htm) and I'll have to agree..
