I am having difficulty with a configuration on an 1841 router. I am just trying to connect the 2 ethernet interfaces to different IP networks and route between them. When I apply the attached config I am able to ping devices on each network, from the router. I am able to ping each interface on the router, from the router. I am able to ping the local router interface from a device on each local network. I am UNABLE to ping from one device to the other across the router.
I don't think I should need to have static routes to the other networks if they are directly connected. What am I missing?
