I'm trying to filter a specific device from my network. Either MAC or IP address filtering would do the trick, but I have trouble finding the exact Cisco IOS commands to use. My router is a Cisco 870 and the device is connected through wifi (if that makes a difference).
I need a fairly simple setup that I can switch on and off easily. This is for development purposes and I need to simulate connectivity changes to that specific device without bothering anyone else connected to that same router.
ACL seems like a way some people suggest, but I am a noob when it comes to configuring Cisco routers and don't know how exactly to work with them.
The commands Kyle mentioned did not work exactly as typed, but when I ran adjusted commands below, it does not appear to work:
ip access-list extended demo deny ip host 192.168.3.33 any permit ip any any exit interface Vlan 1 ip access-group demo in
Vlan 1 is the virtual interface the device is connected. I also tried running the last line after
interface Dot11Radio 0
but that did not work either. Router does not give any errors, but the device can still access the network. Tips?
