ACLs on the Cisco IDS

If I want the option to access the Cisco IDS 4210 (running 4.0-2-S47) initially from any host, do I have to define ACLs with a list of allowed hosts? When I don't define any (empty list), I find that I can't get to the sensor.

However, in the IDM GUI, Device --> Sensor Setup --> Allowed hosts, I see a different description:

Click Add to add a host or network that has permission to access this Sensor through the network. No entries implies all hosts can access this sensor.

Re: ACLs on the Cisco IDS

You do have to define the hosts allowed. No entries in the list means that there are no hosts are networks allowed. If you want the entire subnet to be able to access the 4210 the put for the IP address and enter in the correct subnet.
