Dynamic 1:1 NAT on the Palo Alto interface.

nson2139 — Thu, 12 Jul 2018 11:11:38 GMT

We are looking at some method where we can dynamically NAT subnets behind the Palo Alto Firewall to pick an IP address from the network defined on the external interface.

e.g. I have the external IP address network defined as 10.100.100.0 /24. The IP address 10.100.100.20 is defined as the IP of the external interface.

In the internal network we have about a few networks defined i.e. 10.10.10.0/24, 10.10.20.0/24, 10.10.30.0/24. We are looking at some configuration where we can do some dynamic NATting for these internal networks to pick up some IP address from the External network defined.

Thanks!!

@nson2139,

I guess I'm missing what you are actually asking for; wouldn't this simply be a NAT policy with the proper addresses defined in the policy?

hi @nson2139

like so (dynamic-ip instead of dynamic ip+port):
