Probably a really rookie mistake, but here goes. I have a Juniper SRX and an Azure VPN Gateway, and they are connected. My on-prem VMs can connect to the Azure VMs via Vnet IP, but the reverse is not working. Neither ping nor TCP connections seem to be working. I've created a route in Windows on-prem to go to the subnet in Azure, but I can't find the VPN Gateway IP in this Vnet at all. The Gateway Subnet just shows the route as associated device, but no IP. Does anyone have an idea?
Did you configure a Local network gateway to communicate back to on prem?
