Multi WAN all in same Subnet

Hello all,

 

I've got an ISP who gives me 3 internet lines (3 separate modems) that are in bridge. Now do all the modem have an IP that is in the same subnet a /24. I can't put the modems in router modus that would be the smart thing to do.

So my example situation is:

Line 1: 10.0.0.2/24 -> 10.0.0.1

Line 2: 10.0.0.5/24 -> 10.0.0.1

Line 3: 10.0.0.10/24 -> 10.0.0.1

 

So the IP is in the same subnet and the gateway is te same.

 

Now i need to do a loadbalance on my FG 81E with 3 lines.

After searching the internet i found 1 option that might work.

 

CLI: config sys settings set allow-subnet-overlap enable end

 

 

 

Could anyone tell me if this  would work?

set allow-subnet-overlap enable is not really recommended. Thus might work.

The better way could be to change the network settings of the modems if possible.

Agreed and static routes would be hard to deploy to the same next-hop if you want load-share. SDWAn would be wise here if not obvious ;)
