  • Just dont open up any ports.
    Per default everything gets blocked.



  • @GruensFroeschli:

    Per default everything gets blocked.

    so u mean u do nothing for rule because it's been block anyway?
    how bout ipscan and portscan from inside network?
    is there anyway to block it ?
    i assume that u say bout "don't open up any port" it's for security from outside network?
    is it ?



  • Yes this is about security against the outside.

    There is no firewall in this reality that can protect against attacks from the inside.
    How do you imagine a firewall should provide protection against traffic that never passes through it?



  • hmm.. u're right..
    but i think someone must made it the protection from inside..
    statistically the attacker comes from insideĀ  :-
    not from the outside..

    OOT i want to ask how do u know the traffic that should be blocked because it's containing virus or attacker that trying to attempt?
    how u do the monitoring?
    i've got no clue about the monitoring process which is i'm using ntop+sniffing
