How to use AGIC when route table needs a quad-zero route

[OmpahDev]

According to this page here - https://github.com/Azure/application-gateway-kubernetes-ingress/blob/master/docs/how-tos/networking.md#with-kubenet - the AKS route table needs to be associated with the application gateway subnet in order for the app gateway ingress to work.

But my AKS route table has an outbound firewall rule that directs 0.0.0.0/0 traffic to a virtual appliance (a third party firewall - note - not Azure firewall) and when I tried to associate my AKS route table to the application gateway subnet, it threw an error that 0.0.0.0/0 must be directed to Internet for the application gateway subnet.

How do I get around this problem?

This is the exact same problem that has been reported in #931 and it appears no solution has been implemented after 2.5 years...

Recent improvements for Application Gateway v2 allow to have 0.0.0.0/0 route to NVA attached to Application Gateway's subnet. At the moment they are in public preview but maybe it is worth checking that.
