[utm 220/120] how to block unauthorised portable routers?

chrisloup
basically, you can have guests or staff using unauthorised portable routers to enable wifi within premises where you shouldn't be having wifi.

    You can make firewall rules that apply only to known MAC addresses.  You can limit handing out DHCP addresses to only known MACs.  Management can make it clear that staff can be dismissed for bringing in or allowing a guest to bring in a WiFi router.  How important is it to prevent this in your environment?

    And you can look at the DHCP leases and/or use NMAP to check for MAC addresses registered to Linksys, Cisco, Belkin, etc.

    I've done this with NMAP on our networks and was able to identify a rogue AP; here's an example:
