Hello everyone,

I have a problem when I create a new rule for SDWan.

Just to confirm, the Foritgiate is the default gateway used by your clients?  If the FortiGate is not in the same network as the clients and there is a router between the client and the FortiGate, it can not learn the client's mac address.

    if this is the case, how can i make it recognize the client's MAC.

    Thanks

    You are not able to recognize mac address when it is never seen in the packet.  Once a router is involved the mac address is rewritten because mac addresses are layer2 and routing is layer3.  You can take a packet capture on the fortigate and see the source mac on the packets to verify. 

     

    If this is the case and you want different policies per device, you would need to look at either:

    - FSSO for domain machines to gather details on the machines and correlate them to IP addresses.
    - Use static/dhcp reserved IP addresses for the machines
    - Collapse the routing to the fortigate so it has layer2 connectivity to the devices.
