2-2 Roaming
Suppose several wireless routers run in the same network. Each wireless router serves as a
BSS that has its coverage range. One wireless client (for example, a notebook PC or PDA) can
roam from one AP to another AP accurately. In that case, the wireless client can communicate
with the other devices within the coverage range of the wireless router.
For roaming in the coverage range of the wireless router by a wireless client, you need to set
the APs properly as follows:
• Set the same SSID for different APs.
• The SSIDs of all the computers and PDAs should be consistent with that of APs.
• All the BSSs must use the same wireless channel.
• If the encryption function is enabled, all wireless routers must be configured with the
same encryption mode and encryption key for establishing connection.
• Wireless routers must keep coverage of uninterrupted wireless signals in the whole
operation environment. Hence, please place wireless routers at appropriate places.

8. Dynamic DNS
Dynamic DNS (DDNS) is mainly used to map fixed domain names to dynamic IP
addresses and vice versa. For a user using a dynamic IP address, after the user obtains a
new IP address when accessing Internet, the dynamic domain name software installed in
the host sends the IP address to the dynamic domain name resolution server provided by
the DDNS service provider and updates the domain name resolution database. When
another user on the Internet tries accessing the domain name, the dynamic domain name
resolution server returns the correct IP address.
Click Dynamic DNS and the Dynamic DNS page appears. In this page, you can configure
the DDNS parameteres.
The following table describes parameters in this page:
Item Description

9. Static Routing
Static routing is a special type of routing that can be applied properly in a network to
reduce the problem of routing selection and overload of data flow because of routing
selection and to improve the forwarding speed of packets. You can set the destination IP
address, subnet mask and gateway to specify a routing rule. The destination IP address and
subnet mask are used to determine a destination network or host. Then, the router sends
packets to the specified destination network or host through the gateway.
Click Static Routes and the Static Routes page appears. In this page, you can add, edit and
delete a static routing rule, and view the current static routing table in the router.

Choose Security Options > WAN Setup and the WAN Setup page appears.
In this page, you can set a default DMZ server and allow the router to respond to the ping
command from the Internet. Do not use the two functions unless it is necessary because
they lead to security risks. DMZ allows all ports of a PC in your LAN to be exposed to the
WA N. Enter the IP address of a PC to set the PC to a DMZ host, which is not restricted by
the firewall any more. In this way, the DMZ host can have mutually unrestricted
communcation with a user or server on the WAN.
The following table describes parameters in this page:
Item Description
Disable Port
Scan and DOS
Protection
This function protects your LAN against DoS attack. Do not disable this
firewall function unless a special situation occurs.
Respond to
Ping on
Internet Port
If you want the router to respond to ping commands from the Internet,
select the check box. The ping command can be used for diagnosis. Like
a DMZ server, this function also leads to security risks. Hence, do not
