Cisco (or is it Mr./Ms. Wave :),

Just outbound NAT should be fine. The fw should
keep track of it from there.

Dear All,

Regarding static NAT, do we need to have both inbound
and outboubnd NAT, or only one outbound NAT is enough
and FW1 is mart enough to know the inbound NAT ?

For example, which one is the most correct :
 
Rule
A.B.C.D -> W.X.Y.Z TCP Accept (outbound)
(TCP established are accepted, so no need for the rule
inbound)

with only this NAT ?
NAT
A.B.C.D->W.X.Y.Z translated 1.2.3.4->6.7.8.9

or with both NAT ?
NAT
A.B.C.D->W.X.Y.Z translated 1.2.3.4->6.7.8.9
6.7.8.9->1.2.3.4 translated W.X.Y.Z->A.B.C.D

Thank you,
