RE: [FW1] Benefit of HIDE NAT Behind Non-Interface IP?



It also enables you to use private addresses
on the link between you and your ISP. Thus,
traffic cannot be routed from the internet,
to your firewall directly (assuming that on
all internal interfacs, you also have private addresses)
Since we have no services using static NAT
on our firewall, only hide NAT for outgoing traffic,
there is no public address that can be used to access
a specific host on the network.
 
At least, that's the theory... whether it holds up..
well.. I guess I'll learn that the hard way one day.

It's a good habit if you can do it. This is done in order not to advertise
the IP of your Firewall.

How would all of you rate the degree of the benefit of making your public
NAT HIDE address that not of the firewall's external interface, but of
another IP, only used for that particular purpose?
 
Thanks in advance.
