    Hi.

    I'm trying to block all udp traffic form/to one of my computer in my local network. Also I want to block all tcp traffic on ports 6882 and above from this particular computer (192.168.1.141).
    This are some variations I've made in iptables:

    iptables -t filter -A INPUT -s 192.168.1.141 -p udp -j DROP
    iptables -t filter -A INPUT -s 192.168.1.141 -p tcp --sport 6882:65535 -j DROP
    iptables -t filter -A OUTPUT -s 192.168.1.141 -p tcp --dport 6882:65535 -j DROP
    iptables -t filter -A OUTPUT -s 192.168.1.141 -p tcp --sport 6882:65535 -j DROP
    iptables -t filter -A OUTPUT -s 192.168.1.141 -p udp -j DROP

    Neither of them works;(
    How can I block unwanted traffic?

    One more thing:

    I use firmware v4.70.6 - HyperWRT 2.1b1 - Thibor
