FGSP session sync on FortiGate-VMs on Azure with autoscaling enabled 7.0.1

FortiGate session life support protocol (FGSP) cluster-sync and session-pickup is automatically enabled on FortiGate-VM instances deployed on Azure with autoscaling enabled.

You can achieve the setup in this example by deploying the template available on GitHub.

The following describes the example configuration:

  • The load balancing (LB) rules of both the external load balancer (ELB) and internal load balancer (ILB) have a floating IP address enabled and session persistence set to the client IP address.
  • Outbound rules are configured to the ELB so that PC15 has Internet access.
  • The FortiGate-VMs have firewall virtual IP address rules configured with the ELB performing destination network address translation so that client access from the Internet to PC15 keeps the original IP address.
  • Client access from the Internet to PC15 has symmetric flow.
To configure FGSP session sync on FortiGate-VMs on Azure with autoscaling enabled:
  1. In Azure, configure the ELB load balancing rules. Ensure that Session persistence is configured to the client IP address and that Floating IP is enabled:

  2. Configure the ELB outbound rules:

  3. Configure the ILB load balancing rules. Ensure that Session persistence is configured to the client IP address and that Floating IP is enabled:

  4. Confirm the configuration in the FortiGate A CLI. The following shows an example of possible output:

When autoscaling is enabled, the configuration syncs between the primary FortiGate to the secondary FortiGate in the virtual machine scale set (VMSS). With FGSP configured, sessions sync to all VMSS members. With the ELB performing DNAT and the firewall VIP policy configured on the FortiGate, original client IP addresses are kept.

FGSP session sync on FortiGate-VMs on Azure with autoscaling enabled 7.0.1

FortiGate session life support protocol (FGSP) cluster-sync and session-pickup is automatically enabled on FortiGate-VM instances deployed on Azure with autoscaling enabled.

You can achieve the setup in this example by deploying the template available on GitHub.

The following describes the example configuration:

  • The load balancing (LB) rules of both the external load balancer (ELB) and internal load balancer (ILB) have a floating IP address enabled and session persistence set to the client IP address.
  • Outbound rules are configured to the ELB so that PC15 has Internet access.
  • The FortiGate-VMs have firewall virtual IP address rules configured with the ELB performing destination network address translation so that client access from the Internet to PC15 keeps the original IP address.
  • Client access from the Internet to PC15 has symmetric flow.
To configure FGSP session sync on FortiGate-VMs on Azure with autoscaling enabled:
  1. In Azure, configure the ELB load balancing rules. Ensure that Session persistence is configured to the client IP address and that Floating IP is enabled:

  2. Configure the ELB outbound rules:

  3. Configure the ILB load balancing rules. Ensure that Session persistence is configured to the client IP address and that Floating IP is enabled:

  4. Confirm the configuration in the FortiGate A CLI. The following shows an example of possible output:

When autoscaling is enabled, the configuration syncs between the primary FortiGate to the secondary FortiGate in the virtual machine scale set (VMSS). With FGSP configured, sessions sync to all VMSS members. With the ELB performing DNAT and the firewall VIP policy configured on the FortiGate, original client IP addresses are kept.
