Can I use VMs (backend pools) on different virtual networks to the application gateway?

When I try, the VM list is empty.



You can, but the virtual networks must be connected.


An application gateway can communicate with instances outside of the virtual network that it's in. As a result, the members of the backend pools can be across clusters, across datacenters, or outside Azure, as long as there's IP connectivity.

  • Thanks for this. I have peerings configured both ways... But nothing in vm list. Will it take private IPs? – Beakie Oct 16 at 16:31
  • Yes, it will not let you directly select VMs if they are not connected to the same VNet, but you can just type in their IP addresses. – Massimo Oct 16 at 16:39
  • Great, thank you... – Beakie Oct 16 at 16:43
