Re: [FW-1] Preventing translation of source addresses of packets going to ex tranet segment



-----BEGIN PGP SIGNED MESSAGE-----

Easy as pie, just create a NAT rule in the ORIGINAL side of your NAT
rule base as follows;

ORIGINAL                                                TRANSLATED

Source          Destination                     Source          Destination
Internal_Net    Extranet                        ANY                     ANY

This basically says to the firewall that when your internal net talks
to the extranet keep it's original IP.

Subject: [FW-1] Preventing translation of source addresses of packets
going to ex tranet segment


Hello all:

We are NATing internal private addresses when they go out to the
Internet
through the external interface of our Checkpoint firewall. Source
addresses
of packets going to devices on our extranet segment on the extranet
interface are also getting translated. How do I prevent this from
happening?
I want to retain the original private source addresses of the packets
when
they hit the extranet.

Andy
