how to leave mangle table?

[tbsky]

hi:
  i try to set some rules at mangle table.
  if rule 1 match, rule2 seems still be checked.
  can i leave mangle table if rule 1 match?
  eg: if rule 1 match, then rest of rules are not checked,
      just like filter table..
  do i need to create a new chain to do this?

example:
rule1: iptables -t mangle -A PREROUTING -s 10.1.1.2 -j MARK --set-mark 1
rule2: iptables -t mangle -A PREROUTING -s 10.1.1.0/24 -j MARK --set-mark 2

Regards,
