Paloalto Firewall and VPC peering

L2 Linker

i am confuse AWS network firewall and peering section.
As per AWS documents, it said
**AWS Network Firewall cannot be deployed to inspect traffic between VPCs that are peered together; **

this mean AWS network firewall cannot support.

 

So let me know paloalto can support below scenario ?

 

i did vpc peering VPC 1 (10.1.1.0/16)and VPC2 ( 10.2.1.0/16).


VPC 1 have one private subnet ( 10.1.2.0/24) behind the PA firewall
VPC 2 have one private subnet ( 10.2.2.0/24) behind  the PA firewall
I have the one private route table destination 10.2.2.0/24 next hop is firewall interface in VPC 2.
I add one route to go 10.2.2.0/24 next hop is peer ID in VPC one private route.
I have the one private route table destination 10.1.2.0/24 next hop is firewall interface in VPC 1.
I add one route to go 10.1.2.0/24 next hop is peer ID in VPC 2.

let me know this traffic will pass firewall ?
can we use PA firewall to inspect traffic of private network(10.1.2.0/24 and 10.2.2.0/24) of  two vpc which it is peering?

 

I don't want to use transit gateway.

This would be true if you were only using AWS native constructs but introducing the Palo Alto FW in the "Transit" VPC would allow you to pass traffic/inspect traffic by sending traffic to a VPC subnet ENI resource to another subnet ENI resource. In effect, the Palo Alto FW becomes the "transit router" for the VPC.

VPCs as AWS native constructs are non-transitory in nature but a FW can act as the bridge.
