Clone MAC Address

device, the MAC address of the Barricade must be changed to the MAC

DNS
A Domain Name Server (DNS) is an index of IP addresses and web 
addresses. If you type a web address into your browser, such as 
www.smc.com, a DNS server will find that name in its index and find the 
matching IP address: xxx.xxx.xxx.xxx. Most ISPs provide a DNS server 
for speed and convenience. Since your Service Provider may connect to 
the Internet with dynamic IP settings, it is likely that the DNS server IP’s 
are also provided dynamically. However, if there is...

Lease Time The length of time the DHCP server will reserve the IP 
address for each computer. Setting lease times for shorter 
intervals such as one day or one hour frees IP addresses after 
the specified period of time. This also means that a particular 
computer’s IP address may change over time. If you have set 
any advanced features such as DMZ, this is dependent on the 
IP address. For this reason, you will not want the IP address 
to change.
IP Address Pool The DHCP...

Access Control
Using the Access Control functionality, you can restrict access based on 
MAC address. Each PC has a unique identifier known as a Medium Access 
Control (MAC) address. With MAC filtering enabled, the computers 
whose MAC address you have listed in the filtering table will be able to 
connect (or will be denied access) to the Barricade.
