Subject: [FW-1] Basic NAT question
Hi,
NAT has always confused me and probably will always do. So please have
some patience with me :) Question. Say you have a very common network
topology: Internal, DMZ, External (Internet). You use an automatic
HideNAT rule to hide your internal network behind the external gateway
IP address. This will create two rules, one saying that internal talking
to internal will not be natted while internal to any will be natted.
Does that mean my traffic to the DMZ is also natted? (because the
automatic rule created source:internal, destination:any ->NAT(H))?
>>>yes
If that's true, automatic NAT means a lot of work eventually because you
have to explicitly turn off natting between the segments that you don't
want natted.
Does that make any sense? :)
>> in a way, yes
What is everyone using here? Manual or automatic NAT?
>>both
Thanks
Sascha
