Have a Cisco Router 2811 with a HWIC that gives it an extra port so I have 3 Ethernet ports. Have it configured like this:
FA0/0- 192.168.1.1 FA0/1- 192.168.10.1 FA1/0- 10.0.0.1 (outside)
All that works fine except the .1 and .10 networks can talk and ping each other. Is there anyway to separate them so they can't see the other one but both can still access the internet?
