Hi,
I have installed 3rd NIC in SME.
1st NIC = ADSL
2rd NIC 192.168.1.1 / 255.255.255.0
3rd NIC 192.168.2.1 / 255.255.255.0
Everything is working as it should.
What I need to do is to block IP packets from 192.168.2.0 to 192.168.1.0 network and vice versa.
Of course internet should work in both cases , just packages among those two networks should be stoped.
Probably there must be some solution with iptables scripts since routes are existing in all directions.
thx
Damjan
