Fortigate 100A & Dual WAN

Hello,

We have the Fortigate 100A and we have connected  2 ISP to WAN ports. 

config system interface
    edit "wan1"
        set vdom "root"
        set ip X.X.X.X 255.255.255.0
        set allowaccess ping
        set gwdetect enable
        set detectserver "8.8.8.8"
        set log enable
        set type physical
        set alias "ISP1"
    next
    edit "wan2"
        set vdom "root"
        set ip X.X.X.X 255.255.255.224
        set allowaccess ping
        set type physical
        set alias "ISP2"

 

We have Static route:

config router static
    edit 1
        set device "wan1"
        set gateway I.S.P.1
    next
    edit 2
        set device "wan2"
        set gateway I.S.P.2
        set priority 100

 

How to do that the slow internet from ISP1 (ping> 800ms), it has switched the default gateway to ISP2 ?

Hi Jan.  Can you rephrase this question?

If I'm correct, you want the FGT to choose the other WAN link if the current link has ping delay >800ms, right?

Yes yes

Okay then, but I'm not sure about which version of FortiOS your 100A is running with.

 

If you could execute "config system virtual wan-link" on your device, you could set the threshold as 1000ms for switch-over.

 

So check the command first please.

I think Jan already indicated 4.0 MR2 in his original post, and I believe ForiOS support for for 100A ended at 4.0 MR3.  Wasn't "virtual-wan-link" introduced in 5.2?

I agree with you. FGT 100A might not have that feature.
