    Sruli Saurymper started a new discussion, iptables rules

    iptables rules

    Firewall

    I checked my iptables rules and I don't understand some of the default rules,

    1. Why the separate "RELATED,ESTABLISHED" rules? why not 1 for each interface to cover all ports?
    2. for INPUT there are no "RELATED,ESTABLISHED" rules below port 1024, how does this work?



    Why do we need DHCP port open on the WAN interface?
