    Question iptables port blocking [in & out] - which open, which filtered?

    Hey everyone, how do you handle your firewall? Blocking all incoming traffic and open the related ports for incoming Traffic like 80, 443, 8443 and so on, and do you block also all outgoing traffic and open the related ports for outgoing or just let open all ports for outgoing traffic? Thanks :)
