Print Page - Dual uplink setup help request

My problem is to understand if EFW can handle my (very simple) topology and, if it can, how to set it up.

I have:

two modem/routers connected to the Internet
--- ModemA: ISP_A dynamic IP
--- ModemB: ISP_B routable IP
a single server which should be reachable from the Internet
a small home LAN (wired+WiFi Access Point)

I would like to place the two modems on RED, Server on ORANGE and everything else on GREEN.

Code:

                                *****INTERNET*****
                                |                |
                              ModemA           ModemB
                          (192.168.6.1)    (192.168.6.2)
                                |                |
          RED (192.168.6.0/24) =====================
                                        |
                                  (192.168.6.3)
                              +--------EFW--------+
                        (192.168.8.1)       (192.168.7.1)
                              |                   |
    ORANGE (192.168.8.0/24) =====      ===================== GREEN (12.168.7.0/24)
                              |         |    |    |       |
                           Server      PC1  PC2  PC3  WiFi-A.P.

The only quirk is double modem/routers on RED.

Specific needs are:

use ModemA (dynamic IP) as default uplink.
redirect all ports from ModemB (routable IP) to Server
use ModemB as uplink for Server
have some ping off-site to detect loss of connection on Modem A/B (2 different ISPs)
automatic failover in case one modem disconnects for any reason
incoming connections would be lost if ModemB is down, but that can't be helped AFAIK

I have seen "topic=1912.0", but I seem unable to add a second RED interface, reason
is it's not a second interface at all, but a second gateway on RED, in the same LAN segment.

Is this possible?
I don't have a fourth physical NIC on the machine I plan to use for EFW, I could add another
IP address on the same device, but I'm unsure.
Can someone advise, please?
I am just now playing with EFW so I might have missed something "obvious".

TiA!
