Fortigate – Routing DSCP Tagged Packets Through Different WAN Connections

dscpfortigatefortinetrouting

I have 3 WAN connections and a remote site with a single WAN address.
What I'd like to do is monitor the latency towards the remote site using a single machine (Opsview) on our LAN but through all 3 WAN links.
I know I can tag the packets using DSCP but I wasnt able to determine if it's possible to route the traffic via the Fortigate unit accordingly.

You want to configure up policy based routing. In the gui this is found: Router > Static > Policy Routes. You can do this by using TOS rather than DSCP.

WAN1: Incoming interface: LAN Source Address: Opsview Machine IP Destination Address: Remote Site WAN IP TOS: Assigned Value Outgoing Interface: WAN1 Gateway Address: Next-hop for that WAN.

Do the same for the other WAN links changing the appropriate values.
