I'm curious about why the Linux box couldn't be configured to do the same job as the Cisco router also. Let us know if your Linux colleagues tell you. Wouldn't that be great if they could put the Linux box back and give you the router for your home lab? ;-) Thanks for a great discussion. Priscil

Thanks for your explanation - I can understand my setup very clearly now. I originally asked this question because I have not been exposed to that situation before (I'm at the CCNA level). You are correct in saying that the cellular box does routing for the 192.168.2.0 network. I was also incorrec

The router doesn't know there are 2 segments on the Ethernet. The static route is routing packets destined for the 192.168.2.0/24 to 192.168.0.100. That device is also doing routing. Linux box I think. My question is how does 192.168.0.100 know of both subnets. Does it have 2 interfaces? I'm

This is not the classcial router on a stick model. That model is for routing between VLANs on a router with 1 interface using trunking. All this router is doing is taking packets from its eth1 interface, comparing them to its routing table and forwarding out the same eth1 interface for the gateway

The "router on a stick" effect comes from this: ip route 192.168.2.0 255.255.255.0 192.168.0.100 All traffic destined to any network not on 192.168.0.0 goes to the gateway (192.168.0.1) on interface ethernet 1. The router then re-routes 192.168.2.0 traffic back on the 192.168.0.0 network to 192.

Yes, I have installed a few. It is called a 'one-arm router' or 'router on a stick'. Cisco has some doc's on it, but I would doubt that the hub is a hub. One-arm routers make use of vlans assigned to sub-interfaces. Although I am sure by just assigning the sub-intf the proper segment and the route

192.168.0.100 is what is doing the real routing then for 192.168.2.0/24. If you follow the path, from a 192.168.0.20 machine to 192.168.2.20 say, it goes from 192.168.0.20, to the default gateway, 192.168.0.1 which checks the route table and sends it to 192.168.0.100 (which is on the same network

Can you post the config of the router? Does the Ethernet interface have sub-interfaces? One for each subnet? The answer is probably in the configuration of the interface on the router. What IP and Subnet mask does it have? Could be that the subnet mask of the router Ethernet is 255.255.240.0
