SD-WAN - DHCP AND STATIC

[supportombm]

Hi everyone!

I have a FG30E with 6.2.2 with 3 ISP's. 2 cable and one 4G LTE ( New one)

WAN 1 ip 10.X.X.2 with gateway 10.X.X.1 (Wich is our provider's router) with DMZ on our firewall

WAN 2 ip 192.X.X.2 with gateway 192.X.X.1 (Wich is our provider's router) with DMZ on our firewall

LTE Router in bridge mode with DHCP configured on my firewall

All connection work fine, i get dhcp IP from LTE, WAN 1 work goods, WAN 2 same.

I'm trying to configure SD-WAN but whenever i enable LTE Interface WAN 1 go down with no reasons; BUT WAN 2 remain UP.

SD-WAN is configured with correct gateway.

I've found that no route exists for WAN 1 in routing monitor

hm usually with static ip setup you have to enter the gateway in the sd-wan settings for that interface.

if it does dhcp you don't need to do so.

Works fine here this way
