Hello team, I have come across a difficult situation to solve.
I need to configure a data link interface on my fortigate with the following scenario:
There is a private network between the internet modem and the firewall being (example):
172.16.10.21 - modem interface
172.16.10.22 - firewall interface

Public range: 186.238.30.32/29

When configuring the ip 172.16.10.22 on the fortigate interface, SD-WAN always detects that the link is down. Any idea how to solve this?

SD-WAN will by default use the interface's IP as source-IP.
If your setup is expected to use an IP from the 186.238.30.32/29 range to talk to the internet, you will need to instruct SD-WAN to do so.

The easiest way is probably setting the "source" option in SD-WAN members:

config system sdwan

config members

show # check which ID you want to edit
edit <ID>

set source 186.238.30.X

end
