NAT vs Packet filter

Are NAT/DNAT rules independent of Packet filter rules?

For intsance, if I have a NAT/DNAT rule that says:
source=any --> destination=externalAddress / Service=chat
no source change --> change destination=chatServer --> no service change

Do I also need a Packet Filter rule that says:
Source=any --> Service=chat --> Destination=chatServer ALLOW ?

Please advise.

Thanks,
Claudie

Thanks for the input Simon.

I lived in Perth for 3 months while on vacation...I wish I could move there for good.

Yeah Perth is a nice city, very green. Bit dull though for some people. We've been likened to a giant retirement village [:)]
