Routers on the same fiber optic cable but with different IP addresses on different subnets
To configure more than one IP address on an interface, issue the ip address command with the secondary keyword in interface configuration mode. Routers configured with secondary addresses can route between the different subnets attached to the same physical interface. The SFP of R1 is configured as DHCP client to get a public IP address. Connected to each of them is a Belkin RT3200, both running OpenWRT 24. x (and vice versa) The vilfo is special router. When a router is connected to another router, and the two routers are connected to different network segments, in order for the two network segments to communicate, we need to configure static routing. I have a standard landline DSL (Slow transfer speed, decent latency) via a Fritzbox 7490 and a connection via Cable (High transfer speed, horrible latency) via a. Since you have different subnets on each side of the VPN/fiber you might want to keep this setup, that allows you to separate/filter the traffic between locations AND requires the least changes on devices at both sides.
