Hello to all. I have a device that is connected to lan of ER605 vpn router. This router has 3 wans connected. This device has 3 options to send packets to each gateways separately for a registration method. When i try to set each Wan IP to same subnet as a router (with dhcp disabled) it says error and cannot save this setting. In the device i have to set Gateway 1, Gateway 2 and Gateway 3. It needs this for a registration process with username and password for each gateway. If someone can help, thank you very much.
