Connecting Azure Site-to-Site VPN to On-prem Gateway with 2 public IP's

  • 772

I have a cisco ISR on-prem with 2 endpoints (primary and secondary) and I want to connect my Azure VPN Gateway to both endpoints through a single connection (same local address space for both IP's).

When creating an Azure local network gateway I can only enter 1 public IP address, not 2. Is there a way to connect with 2 IP's from the Azure VPN Gateway?

Thank you

    Can't be done the way you are asking. You have a couple options. You can set up both onprem Devices to the same VPN Gateway.

    Multiple on-premises VPN devices

    Or, you can set up a full mesh.

    Active-active VPN gateways
