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).

Make sure that default access status to the administrator PC appears as ‘allow’
under the
system | access | access control
