Title: Question on NAT


NAT Rules


rule 10 to non-nat to internal networks :
| MACHINE-A | internalnets  |  any  -->  | original | original | any

rule 11 to nat to dmz1
| MACHINEA | DMZ1 | any  -->   | MACHINEA-NAT | DMZ1 | any

rules 12 to NAT to internet
| MACHINEA | any | any  -->  |MACHINEA-NAT-INTERNET | any | any


This is my initial setup, I use Hide NAT in rule 11 and 12.

When applied, rule 10 is bypassed and machinea to DMZ is NATed using rule 12 ?!?! why?

Now, I moved rule 10/11/12 to 1/2/3 and changed the Hide NAT to Static for rule 2/3 (old 11/12)

And now it works... any idea why ?

What is the difference between static and hide NAT ? As far as I can see, I could not use static source NAT with 2 different sources... But it seems to work anyway...


Also, anyone got Secureclients working through a stonebeat fullcluster? Even with a policy server behind the cluster , the topology is corrupted (no policy server in it, even if it is defined properly)...


And last question, anyone got FreeBSD IPsec working with Checkpoint ? if so, can you send your kame.sh file to the group ?

Here's another one... :-)

Is it possible to do VPN between a cisco (in fact , any non-checkpoint IPsec VPN) and a checkpoint/stonebeat fullcluster using the clusters IP? or Do I have to use 1 of the 2 IP's ??


Thanks a LOT !!
