Fortigate 60E SDWAN rule not work.

I have an ADVPN setup between Hub and Spoke. At the Spoke, I get BGP routes like that.

 

LAN - HUB(WAN1) - SPOKE (WAN1) - LAN

For eg, I tracert from my local subnet to 192.168.25.0/24 or 192.168.50.0/24, it should go to 10.10.2.x ..., but tracert result alway show that, it go directly to WAN' gateway and time out IP like this:

Can you help give me any keyword or hint, so I can resolve this issue?

Hello @downlinkvip1 ,

 

Welcome to the community.

Can you paste the output of "get router info routing-table database".

You also mention that the SDWAN rule is not working.  Can you provide some details about the configuration? Have you configured any health-checks? If yes, what is the state?

downlinkvip1

Hi @aionescu,

Indeed, after a few days, I even deleted the SDWAN rule. So, the traffic will go based on the routing table, right?

I still got the error. For eg, 192.168.25.1 will go through the tunnel but 192.168.25.2 will go directly to WAN gateway.

Hi @downlinkvip1 can you share also the output of get router policy

 

Also, make sure there is no session between the communicating hosts and then generate the traffic while running the following commands:

 

diagnose debug flow filter addr x.x.x.x <------ where x.x.x.x is the source of the traffic
diagnose debug flow trace start 100
diagnose debug enable

..................

then show the session with:

 

diagnose sys session filter src x.x.x.x where x.x.x.x is the source of the traffic
diagnose sys session filter dst y.y.y.ywhere y.y.y.y is the destination of the traffic
diagnose sys session list

downlinkvip1

Hi @aionescu 

"get router policy" shows nothing.

 

At this weekend, I will run debug command and send to you. Thank you!

downlinkvip1

Hi @aionescu ,

I just use your debug command to troubleshoot the connection from HQ' host 192.168.1.10 to Br'host 192.168.90.188 (through ADVPN) and get this log.

The gateway of branch subnet 192.168.90.0/24 is 192.168.90.254 (is a VLAN interface at physical Fortigate port 7). 

 

From HQ site, we can ping to 192.168.90.254 (through ADVPN), but can not ping to 192.168.90.188. 

 

Please kindly help as I don't know why branch Fortigate not forward packet out port 7 or something like that.
