Does anyone know how the data is processed? Does it perform a lookup if it is, ie: icmp,tcp,udp etc or does it store it in numeric form? -----Original Message----- From: netfilter-admin@xxxxxxxxxxxxxxxxxxx [mailto:netfilter-admin@xxxxxxxxxxxxxxxxxxx] On Behalf Of Alistair Tonner Sent: Wednesday, June 02, 2004 11:14 AM To: netfilter@xxxxxxxxxxxxxxxxxxx Subject: Re: Destination Nat On June 2, 2004 07:19 am, John A.
