    If you are talking about Vlan in the catalyst switch, forget it.

    I should still be able to insert the Untangle server between the Primary Firewall and the Catalyst switch.

    All that would mean is, all data would be flowing through and if ever the Primary Firewall fails. I wold not be monitoring the Backup Firewall until l the Primary was fixed. right?

    Yes
    At least you can test the features of Untangle, if they are good for you, can re design your edge network or put 2 untangle.

    We do have untangle failover options now. Passive bridge mode fail over and active passive fail over for routers. While the latter of the two is much more expensive to implement, it is possible none the less.

    Passive fail over uses fail open network adapters for bridge mode installs. If untangle fails, power fails, or hardware fails, the card physically bridges the lan/wan ports and acts as a network hub. While untangle will not be filtering traffic, the network will continue to have internet access.

    active passive is a bit more complex. You have a device called a wan switch, which connects to your ISP modem or router. It has 3 ports, a wan, and 2 lan. You connect the wan port to your ISP modem, a primary untangle device to lan 1, and a failover untangle device to lan 2. The wan switch monitors lan 1 and 2 by sending packets to both devices and waiting for a response. If it does not receive one, it considers that port to be failed, and will switch traffic to the remaining active port. So if your primary untangle fails, the secondary untangle will take over, with no network or packet loss.
    Behind untangle 1 and 2, you have a cisco or similar router with no nat enabled. This is your network default gateway for your client computers. Configure the router to use untangle 1 as the default route. Configure the router to use untangle 2 as the fail over route if route 1 is down. This can be achieved using various routing protocols. This way, if untangle one fails, the router will know this and use the higher metric route, which will be untangle 2. I am pretty sure this can be achieved with a switch or other means that I may have not thought of.
