    Also in the tutorial this is to be run on a local NTP server and not on the server your configuring in the tutorial.

    You put this in iptables on a local NTP server to accept udp traffic inbound from the server your configuring in the tutorial I believe.

    David, it appears that your iptables command is invalid and does not match an iptables chain, match or target.

    Your iptable command looks to be failing because “RH-Firewall-1-INPUT” is not a valid ip tables chain. Your match (-m) and target (-j) look correct.

    You can view configured chains via CLI command iptables -L
    Verify there is a chain matching RH-Firewall-1-INPUT which your command says is the name of the chain that isn’t matching.

    Typical chains would be INPUT, OUTPUT, and FORWARD that I typically see but there can be others and user defined chains as well.
    You can create a new user defined chain to append the iptable entry to by using the iptables -N <chain name> command if you need a new one but I think in this scenario if “RH-Firewall-1-INPUT” is not listed as a valid chain you could substitute just the INPUT chain so the entry would start as “iptables -A INPUT -s …” instead.

    I would write this like so;
    Iptables INPUT -s 192.168.1.0/24 -m state –state NEW -p udp -dport 123 -j ACCEPT

    Hope this helps.
