4.23 What is Maximum Transmission Unit (MTU) Size?
Maximum Transmission Unit (MTU) indicates the network stack of any packet is
larger than this value will be fragmented before the transmission. During the PPP
negotiation, the peer of the PPP connection will indicate its MRU and will be
accepted. The actual MTU of the PPP connection will be set to the smaller one of
MTU and the peer’s MRU. The default is value 1400.
4.24 What is Clone MAC Address?
Clone MAC address is designed for your special application that request the
clients to register to a server machine with one identified MAC address.
Since that all the clients will communicate outside world through the X-Micro
WLAN 11g Broadband Router, so have the cloned MAC address set on the
X-Micro WLAN 11g Broadband Router will solve the issue.
4.25 What is DDNS?
DDNS is the abbreviation of Dynamic Domain Name Server. It is designed for
user own the DNS server with dynamic WAN IP address.
4.26 What is NTP Client?

4.27 What is VPN?
VPN is the abbreviation of Virtual Private Network. It is designed for creating
point-to point private link via shared or public network.
4.28 What is IPSEC?
IPSEC is the abbreviation of IP Security. It is used to transferring data securely

4.29 What is WLAN Block Relay Between Clients?
An Infrastructure Basic Service Set is a BSS with a component called an Access
Point (AP). The access point provides a local relay function for the BSS. All
stations in the BSS communicate with the access point and no longer
communicate directly. All frames are relayed between stations by the access
point. This local relay function effectively doubles the range of the IBSS
4.30 What
