Trying to setup network failover with lan to wan configuration
-
I currently have two routers running in my small business network setup. One is setup for the main network and is my Fortinet 80f. It currently has a 1gb circuit from ISP 1. The other is a Pfsense sg-3100 which is set up for our Kraft's team only and it has its own 1gb circuit from a different ISP. My problem is the ISP on my main router is pretty crappy and has outages all the time. I would like to utilize the 1GB on my 2nd router for failover. I figured there must be a way to configure the lan port on the pfsense router to be able to utilize the circuit on the main router. Any ideas on how i should proceed with this configuration? vlans, bridge mode,??? help please!

Ideally you want to setup a separate subnet (a transport network) between them that isn't used anywhere else. Doing that avoids any asymmetric routing issues that might otherwise hit.
So, yes, you could use a VLAN between them with nothing else on it if you have a physical link already in place. Or just a separate link if you're adding it.
Otherwise there's nothing special required in pfSense, it just sees the Fortinet as a host and routes it's traffic. It becomes more complex if you want, say, the pfSense LAN clients to be able to reach the Forinet LAN clients. Easily doable if you have a transport subnet to roue across.
