Connectivity Issue b/t On-Prem & Azure VNET via S2S VPN

Question

We are having bit of an issue with connectivity from On-Prem to Azure VNet as we are working to standup a new infrastructure in Azure.

·         2 Vnets currently configured (Vnet1 & Vnet2)

·         Vnet Peering is configured between the Vnets

·         Connectivity between servers between VNets works

·         Site-to-Site VPN Tunnel configured b/t Azure and On-Prem (status is connected)

·         On-Prem systems can successfully connect to Vnet 1

·         On-Prem systems are unable to connect to Vnet 2

·         I’m wondering if it has something to do with the VNET peering configuration

Answer 1

Hi @Kalel ,

did you set the routes correctly?

Routes on-premises to vNet1 and vNet2 (using VPN)?

Routes from vNet2 to on-premises (using a routing instance in vNet1)?
