I am using a Cisco 857. Most PC's on the LAN are using IP range 192.168.1.0. I have created another network on 192.168.20.0, and another on 192.168.23.0.
I have added the commands
ip route 192.168.20.0 255.255.255.0 vlan1
ip route 192.168.23.0 255.255.255.0 vlan1
From PC's on the 192.168.1.x range, I can ping PC's on the 192.168.20.x range, but cannot ping anything on the 192.168.23.x range.
The network settings on the PC's are the same - both using the router as a gateway - is there anything else that I'm missing?
