quick question on iptables

Hello,

    We know that for filter table, there are three built-in chains in which we can place the firewall policy rules. They are forward chain, input chain and output chain.

  My question is if the policy rules for filter table in all the three chains have to be the same or can they be different??

Thanks a lot!
