To implement Microsoft VPN Forced Tunneling, you need to perform the following steps:
- Configure a Virtual Network Gateway or Virtual WAN Gateway: You need to create and configure a Virtual Network Gateway or Virtual WAN Gateway in Azure. This gateway is responsible for establishing the VPN connection between your on-premises network or remote clients and your Azure virtual network.
- Configure a VPN Connection: You need to configure a VPN connection between the Virtual Network Gateway or Virtual WAN Gateway and the on-premises network or remote clients. You can configure the VPN connection using either Point-to-Site (P2S) or Site-to-Site (S2S) VPN, depending on your network requirements.
- Enable Forced Tunneling: You need to enable Forced Tunneling on the Virtual Network Gateway or Virtual WAN Gateway. To enable Forced Tunneling, you need to create a User Defined Route (UDR) with a next hop type of Virtual Network Gateway or Virtual WAN Gateway, and then associate the UDR with the subnets that require Forced Tunneling. This will ensure that all traffic from those subnets is forced to traverse the VPN tunnel.
- Configure Routing: You need to configure the routing on the on-premises network or remote clients to route all traffic through the VPN tunnel. This can be done by adding a static route or by configuring a routing protocol such as BGP.
- Verify Forced Tunneling: After configuring Forced Tunneling, you should verify that all traffic from the subnets associated with the UDR is traversing the VPN tunnel. You can use network monitoring tools to verify that the traffic is being routed through the VPN tunnel.
To implement Microsoft VPN Forced Tunneling, you need to create and configure a Virtual Network Gateway or Virtual WAN Gateway, configure a VPN connection, enable Forced Tunneling, configure routing, and verify that traffic is being routed through the VPN tunnel.
