    Linux IP table PORT blocking issue

    Hi.
    I am a VPN ( Virtual private network ) service provider.

    I want to block outgoing port 6881 on my linux debian server with following commands :

    vpn1:~# iptables -A OUTPUT -p tcp -dport 6881 -j DROP
    Bad argument `6881'
    Try `iptables -h' or 'iptables --help' for more information.


    But i am getting error.
    Please Help me !

    It should be "--dport" (two dashes).
