Access Restriction (ezTCP Firewall)
On the [Option] tab of ezManager, you can set access restriction function with MAC and
IP address.
Allowed MAC Address
If this option has a valid value, the device which has the MAC address is only
permitted to access.
Allowed IP Address
This is for qualifying hosts with IP address or range of IP addresses. The range is
defined by multiplying [IP address] and [Network Mask] in bit unit.

7.2.1 Setting Password
A password can be used for protecting CSE-H53N from TELNET login or changing
environmental parameters by hosts which are not qualified. The maximum length is 8 bytes
of Alphabet or number.
When you want to revoke all of these restrictions, operate CSE-H53N as ISP mode. In
the mode, all restrictions are removable and communication with ezManager is
revoked.
