Hello everyone  I have the following problem. WAN1 is set up with a static IP. WAN2 with a dynamic IP. Default Moderate is that DHCP has a distance of 5 and Static has a distance of 10. I adjusted the DHCP. So now my problem is I am not getting any traffic over WAN2 If I change the distance to 10 or 5, WAN 2 works, but WAN 1 no longer works. I've also tried administrative distances. Unfortunately also without success. Does anyone have any other ideas or can I see something. Thank you very much for your help

Surprisingly, it often happens that one of the WAN links doesn't work. But also misconfigurations happen. Can you reach something over internet when using the source-ip of the wan2?

exec ping-options source x.x.x.x

exec ping fortiguard.com 

 

Then check the routing: get router info routing-table all

> when the problem happens. That will tell you where the traffic should go

 

And run a packet capture to see where the traffic actually goes. For example:
ping 8.8.8.8 from your PC, run a packet capture :

diag sniffer packet any "host 8.8.8.8 and icmp" 4 0

Yes, I can achieve everything via Wan2.

That is not a valid answer without data to support it.
We can't guess what you are doing wrong without outputs. Since this is a public space, you may want to open a support case to get support.
