Redundant Failover Internet Connection for SMB

[VirtuousVigor]

Hello,

Can anyone confirm and or suggest/recommend a procedure for setting up a redundant failover internet connection as a secondary uplink in case our primary gets interrupted so the secondary connection can take over and ensure business data communication still goes out and comes in?

We use pfSense on a SG-8860 1U firewall set up.

My CEO is asking about backup internet connection whenever our primary ATT fiber line goes down (as it has in the past) at a cost less than 200 a month.

I have never done something like this. I figure it would be through some other physical medium and another provider service I think.

Is there some feature in pfSense I must resort to in order to apply this as well? Load Balancing for Uplink time takeover or something?

Or should I just get with ATT as they manage our router to provide a secondary line, such as cable internet, and then configure that on the OPT1 port interface on the netgate firewall appliance.?

I honestly do not know where to begin with this.

Thank you in advance.

@VirtuousMight pfSense 2.4.4 works with gateway groups. It's interesting and I use this quite a lot: https://docs.netgate.com/pfsense/en/latest/routing/multi-wan.html
