Hi list,

What`s the differences between these two groups of rules.?????
In the first i use MARK --set-mark to mark packets and in the other i =
use CONNMARK --set-mark

1.
    # iptables -I POSTROUTING -t mangle -j CONNMARK --restore-mark
    # iptables -I POSTROUTING -t mangle -m mark ! --mark 0 -j ACCEPT
    # iptables -I POSTROUTING -t mangle -m ipp2p --ipp2p -j MARK =
--set-mark 30
    # iptables -I POSTROUTING -t mangle -m ipp2p --bit -j MARK =
--set-mark 30
    # iptables -I POSTROUTING -t mangle -j CONNMARK --save-mark

2.
    # iptables -I POSTROUTING -t mangle -j CONNMARK --restore-mark
    # iptables -I POSTROUTING -t mangle -m mark ! --mark 0 -j ACCEPT
    # iptables -I POSTROUTING -t mangle -m ipp2p --ipp2p -j CONNMARK =
--set-mark 30
    # iptables -I POSTROUTING -t mangle -m ipp2p --bit -j CONNMARK =
--set-mark 30
    # iptables -I POSTROUTING -t mangle -j CONNMARK --save-mark
