So I'm working through an IP migration when I thought of this question that I don't know the answer to and can't find an answer to with my Google skills. Is it possible to assign an IP from the DMZ subnet as a destination NAT? For example, if my DMZ were 184.108.40.206/24, could I assign 220.127.116.11 as a dynamic NAT IP for an internal subnet such as 10.1.1.0/24?
From what zone is traffic coming from and where is it going?
Assuming that traffic comes from internal and goes to dmz and you want to hide whole internal subnet behind 18.104.22.168 then yes you can do it but you do it in Source NAT side not Destination NAT (unless you want to do SNAT and DNAT at the same time).
If traffic is from LAN to Internet and you apply SNAT to this traffic to source from DMZ ip that most likely is in RFC1918 range then first ISP router that sees this packet will just drop it.
Maybe I was unclear. The scenario I'm proposing is I have a DMZ that has a /24 of public IPs. Can I use an IP in that subnet as the IP I'm NATing an internal IP subnet to for the internet (eg. 10.20.1.0/24 ->NAT-> 22.214.171.124) The private IP would never be exposed to the internet.
So DMZ is currently behind Palo but you don't apply NAT just Security Policies?
If return traffic back from internet to 126.96.36.199 get's back to Palo then yes you can do this NAT.
