I have problem with triple dynamic load balancing on my NAT machine. Actually, there is no problem with load balancing but with WAN addresses which are in the same subnet, for example:
* WAN-1= 188.2.../22
* WAN-2= 188.2.../22
* WAN-3= 188.2.../22
Those addresses have the same gateway which get from provider automatically via dhcp-client ether interfaces. By today, I had two WANs with same gateway and that has been working perfectly until I've put third WAN interface and get IP automatically. In that moment, all internet traffic on the network went down totally.
I forgot to mention that WAN-3 interface represents EoIP tunnel to the location where is located one x86 based MikroTik router with ethernet card directly connected to provider's cable modem. On this router, there is one ether card, EoIP tunnel to NAT machine, bridged interfaces and this works extremly reliable.
So, my question is: How to prevent internet traffic goes down on NAT machine when third interface gets IP address from the same subnet and gets same gateway as WAN-1 and WAN-2.
Thank you in advance,
