  • Support for VXLAN on flexible tunnel interfaces (SRX Series and vSRX) —Starting in Junos OS Release 23.4R1, we support VXLAN on flexible tunnel interface (FTI) on Juniper Networks® SRX Series Firewalls (SRX series). To configure FTIs on your device, use the vxlan-gpe parameter under the tunnel-endpoint VXLAN encapsulation at the [edit interfaces interface-name unit logical-unit-number tunnel encapsulation] hierarchy level. When you configure an FTI on SRX series devices, you must also configure the following:

    • A security zone for the FTI.

    • The security policy with security rules for traffic sent to the FTI.
