Multiple providers

WhoYouNow

Good day! Thank you for your answers to the previous questions.
Now I have encountered the fact that having several providers, I have micro switches between them, which lead to a break in communication.
Tell me, where can I correctly configure the broadcast of a certain LAN zone to the provider I need?
Now each provider is in my own WAN zone
Now each local network is in my own LAN zone
Example:

And I have a security policy that didn't work

Hi @WhoYouNow,

Based on your description, it seems that you want to specify which LAN zone sends traffic via a specific WAN interface. You mentioned that you’ve already tried to configure a security policy, but that method did not affect how traffic is routed, because security policies are used to allow or block traffic after the routing decision has already been made.

To route traffic from a specific LAN to a specific WAN interface, you need to use a policy route instead.

Here’s an example based on your scenario to configure the policy route:

• LAN zone: WORK_LAN (192.168.88.1)
• WAN zone: TEST_WAN (101.10.0.200)
• Goal: All traffic from WORK_LAN should go out via TEST_WAN

Configuration steps:

1. Go to Configuration > Network > Routing > Policy Route
2. Click Add
3. Fill in the rule as follows:
   • Incoming Interface: Interface (select LAN as member)
   • Source IP: WORK_LAN (Specify the LAN zone)
   • Destination IP: any
   • Next-Hop Type: Interface
   • Interface: TEST_WAN
   • SNAT: Outgoing Interface
4. Apply the rule

Note: Ensure the order of your policy routes is correct, as the firewall processes rules from top to bottom.
