L2 Traffic Forwarding

Hello,

We have the following setup:

Today, there is no firewall separating the switches. Our main goal is to make sure that PC1 is able to connect PC2 using LAYER2 TRAFFIC (no DG) ONLY.

Is it possible to achieve this goal based on the following facts:

1. There's a trunk interface between the switches and the firewall.

2. The VLANs under the trunk are L3.

3. I can't add any more physical ports.

Can I configure VLAN 100 as layer 2 so that broadcast traffic will be forwarded?

Hello @crlic ,

You can achieve this request in two ways.

First, you can connect switches back to back. Second, you can use FortiGate interfaces as a software switch.

You can find more information about software switch in that link.

Hi

In addition to Atlas' suggestion, as alternative you should be able to achieve this using use virtual wire pair.

Or transparent VDOM.

So you have choice depending on your design and requirements.
