    Dear All,
    I have a machine first I run this command service iptables restart
    Flushing firewall rules: [ OK ]
    Setting chains to policy ACCEPT: filter [ OK ]
    Unloading iptables modules: [ OK ]
    Applying iptables firewall rules: [ OK ]
    Loading additional iptables modules: ip_conntrack_netbios_n[ OK ]
    Next when I run this command vi /etc/sysconfig/iptables to insert new ports it gives me a blank page is this normal?

    Dear Falko,
    I am using centos 5.5 but on other machine this is not a problem either.

    You can't create rules by putting them in that iptables file. You create rules by typing:

    iptables and rules here
    Looks like you don't know much about that firewall software. Why don't you use APF instead? It's based on iptables and much much easier to configure ;)

    If you really really want to use iptables, read this pretty good and informative page:

    Dear Jawsh,
    What are APF? What the other firewall software we should know?
