Azure routing tables are not created if the VNet and subnets already exist #7

Open DoctorBizzle opened 4 years ago

DoctorBizzle commented 4 years ago

Scenario:

Azure
Firewall VNet and 4 x subnets already created in rg1
vFTD deployed to Firewall VNet and rg2

Issue:

no routing tables are created for the FTD subnets

Why preconfigure the vnet and rg1?

The FTD deployment will not work if there are any objects in the target resource group
Some people use subnet segregation rather that hub and spoke / multiple vnets.
Some Azure services are unable to traverse VNets, e.g. Azure Bastion.
VNet & subnet can be provisioned by Terraform in advance.
