Service – select services that access you need to control [all/ssh/telnet/snmp].
Telnet service should be also enabled in the system | access | telnet to allow the
telnet access to the controller. Otherwise, the client or network will not get telnet
access.
Network Address – specify the network or host address with netmask in bit format separated by
dash.
The /N stands for the number of bits that are in the network address. There are 32 bits, so we have
32-N bits left that are part of the network. The first N bits of x.x.x.x correspond to x.0.0.0 when N=8,
our network address, and the netmask is 255.0.0.0 (when N=8).

Access – select the access policy: [allow/deny].
Up to 255 different access control rules can be set.
System | Access | Telnet
When the telnet function is switched on, telnet connection to the Hotspot-in-a-Box is enabled and the
administrator can connect to the CLI interface via telnet.
Make sure that default access status to the administrator PC appears as ‘allow’
under the system | access | access control menu. Otherwise, you will not be able
to connect via telnet, even though the telnet function is enabled.
By default telnet is disabled:
