I'm having issues routing between Azure Virtual Desktop deployment across VPN to my on premise network.
Azure VPN configured with Cisco ASA Firewall connecting all Subnets into Azure.
Azure Subnet in production 10.0.0.0/24
AVD subnet 10.0.10.0/24
Both subnets exist in same RG and vnet.
On premise subnet is 172.19.0.0/16
There is no firewall or NSG on the AVD deployment, only a newish NAT GW for routing out traffic to the web from 1 IP.
I can route between the subnets within azure as expected.
Any ideas? ASA ACLs, NATGW issue or??
