I'm setting marks with iptables like this
iptables -t mangle -A POSTROUTING -d 192.168.1.143 -j MARK --set-mark 10
if I want to clear what I do is remove all with
iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
instead of removing all the rules to clear this, how to remove a mark only?
