Multi-WAN with same gateway

Hello,

Our provider (Unitymedia, Germany) is giving us two links with IP addresses from the same network range. Gateway for both of these links is the same.
The IP assignment is done via dhcp reservation. Each link has its own cable modem,  both links have the same speed.

Like this but with public IPs:

Is it posssible to use Multi-WAN with load-balancing? And how is it configured?

Greetings,
Michael

  • I just tried setting this up today and it would not load balance or fail over to the second WAN connection due to them being on the same subnet with the same gateway, even though they do have different IP's.  I talked to support for 2 hours and they tried to make it work, but then said it won't work with the same subnet on 2 different WAN interfaces.  (Our setup is for 2 wireless bridges in-line.)  So I think the next step is to purchase a switch or other such devices that will aggregate the links for me... Unless anyone has other ideas?
