Hey Guys and Gals
I am having an issue getting u-turn nat to work between two isolated networks on the same Palo. I am basically tiring to allow Interanal clients to access a webcam server in a IoT network. I think might issue might be that I need to add a Statement in my Virtual Route or a Policy Based Routing rule. Though the reality is that I probable made a simple error like putting in the wrong zone somewhere. Both network live on a Palo Alto running Pan OS 8.1. I've include a diagram and config below, the names and address have been changed to protect the innocent. I add because I realize that the internal address might not be clear on the diagram. 10.0.x.254 is the internal ip address of the Palo Alto. The internal gateway is 10.0.x.1. I appreciate any help or insight people can provide, and I hope I provided enough information.
Original Packet Tab
Source Zone = Corp Trust, Destination Zone = IoT Untrust, Destination Interface is Any, Service is TCP port 8889, Source Address = Any, Destination Address = 188.8.131.52
Translated Packet Tab
Source Address Tranlation = Translation Type is Dynamic IP and Port, Address type is Interface Address, Interface is 2,
Destination Address Translation = Translation Type is Static IP, Translation Address is 10.0.10.200, translation port is 443
Source Zone is Corp Trust, Source Address is Any, Destination Zone is IoT Untrust, Destination address is 184.108.40.206, Service is 443, Action is Allow.
Virtual Routes Corp
Destination 0.0.0.0/0 next hop 220.127.116.11
Destination 10.0.0.0/24 next hop 10.0.0.1
Virtual Route IoT
Destination 0.0.0.0/0 next hop 18.104.22.168
Destination 10.0.10.0/24 next hop 10.0.10.1
I need to nat the two different subnets. The Corp network needs a dynamic nat so clients can access the internet. The IoT network is using a 1 to many nat because we have multiple web cams and only 1 external ip address dedicated to that network. Thats why I am nating. I will check to make sure it is bi-directional but still trying to figure out how to route the traffic.
