Share custom static routes with a Shared VPC

[mateusotavio]

Hi, 

I've a host project like a shared VPC and this VPC share the subnets with another projects. I'd like to inspect all traffic this subnet with a firewall, so i created another specific project with a normal VPC and connect to a Shared VPC with VPC peering. 

VPC A (HUB - firewall ) <---peering---> Shared VPC (Spoke) with a some subnets shared with another projects.

And i shared a custom static route to the firewall interface in VPC A with a VPC B. But its not working

VPC A - Export routes enabled
VPC B - Import routes enabled

I see the route in Shared VPC with a highest priority, but the traffic does not go to the firewall, but to the Interconnect that exists in the shared vpc

HI @mateusotavio ,

Did you follow any documentations or guides when you set it up? If yes, can you share any link/s of it?

Based from the setup that you shared, only import routes are enabled on VPC A. Are you trying to have a bidirectional traffic between the VPC? Try enabling the `Import subnet routes with public IP` as it is not enabled in the same peering. You can follow this guide for more details.
