Hello,
We have successfully setup a vpn connection with Azure and our datacenter. Say the datacenter network is 172.16.0.0/24. We have several other locations and we cannot access the azure vnet from there. Say these sites are subnets 172.17.0.0/24 and 172.18.0.0/24. How can we make sure that from these subnets, we can access MS Azure machines? Do we need to configure routing in Azure? I thought that was not possible? I have added the 172.17.0.0/24 subnet as a second local network in MS Azure. So my question is, how can Host A on a branch office (in subnet 172.17.0.0/24) can reach HostB in Azure subnet (subnet 172.20.1.0/24). I have added the subnets to "Local networks" in Azure, but that doesn't help. Can it be a routing issue on our side?
What we (example IP subnets) have configured is:
Datacenter network: 172.16.0.0/24
Azure vnet: 172.20.0.0/16, subnets: 172.20.1.0/24 and 172.20.2.0/24, gatewaynet:172.20.0.0/24
Other locations: 172.17.0.0/24, 172.18.0.0/24
The physical locations are all connected via an MPLS WAN.
