To be clear, regarding IP routing:
  • Communication between two addresses on the same subnet do not need routing; the underlying subnet protocol (usually Ethernet) provides the addressing (usually MAC), via Address Resolution Protocol (ARP). This is used between your server and your router on the 192.168.0/24 subnet, between your wireless workstations and your router on the 192.168.1/24 subnet, and betwen your router and your ISP's router, on whatever subnet your router connects to within your ISP.
  • All communications that goes beyond a single subnet must be routed.
  • A subnet with a single router only needs a default route: the IP address of the router on that subnet. e.g.: Your wireless workstations on 192.168.1/24 need only a default gateway of 192.168.1.1; the address of your OpenBSD router on that subnet. Your wired servers on 192.168.0/24 need only a default gateway of 192.168.0.1; the address of your OpenBSD router on that subnet.
  • Your OpenBSD router is connected to three different subnets. It's default route should be to your ISPs router somewhere on the em0 subnet.
