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.

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!
