    Linux Guru help


    by thinknologist ·

    I was doing a personalized firewall and I came up with this command through a book.

    iptables –flush
    iptables –flush -t nat
    iptables -A OUTPUT -j ACCEPT -o lo
    iptables -A INPUT -j ACCEPT -i lo
    iptables -A INPUT -i ppp0 -j DROP
    iptables -A OUTPUT -o ppp0 -j DROP

    I have no problem executing the previous codes but with the codes below, it prompted an error.

    iptables -A OUTPUT -m state -state NEW, RELATED, ESTABLISHED -j ACCEPT
    iptables -A INPUT -m state –state RELATED, ESTABLISHED -j ACCEPT

    Bad Argument ‘NEW,’

    I am asking the Linux gurus to comment on this code. WHAT COULD THE PROBLEM WITH THE COMMAND. I have followed carefully the book but still it prompted me an error. I am stucked here and need help.
