Title: Building a Backup Firewall
Post by: spetrillo on December 20, 2020, 12:34:37 AM
All,

I am in the midst of building a secondary firewall. Can I connect the LAN interface of the new firewall to my current network, so I can get the updates?

Thanks,
Steve

Yes, just add another gateway in System : Gateways : Single, point to your primary and set this as upstream.

Do I connect the LAN side or WAN side of the new firewall?

Can this connection go through a switch or does it have to be NIC to NIC?

Maybe we are crosstalking. You set up Backup Firewall with different LAN IP and instead of creating a gateway in WAN you create one on interface LAN with IP of primary
