If you intend to monitor only, set OUTPUT and FORWARD chains to DROP.
Otherwise you can't firewall. Make sure your monitoring software is up
to date, as vulnerabilities on it will be the biggest issue.

    Hi Everyone,

    Currently, I use ebtables and iptables to secure my servers. It would be 
    appreciated if someone could please give me some advice on what the best 
    settings are for using a network port in promiscuous mode for network 
    monitoring *only*. I.e. I do not want any of this traffic to be able to 
    access anything on my server.

    Thanks
