4.2 Wireless

4.2.1Basic

Multiple SSIDs (VRT-420N Max support the five SSID) allow the ability for separate security mode and
key settings to be set by users for both convenience and increased protection. Users are able to
configure their network devices to access the first SSID with the WP A2 PSK (Pre-Shared Key ) and secret
key, whilst share the second SSID with WEP and the periodically changed key for visitors. In addition,
users are able to isolate these SSIDs to avoid malicious attacks and prevent certain access for visitors
using the second SSID. This then provides users an extremely convenient approach to share the
wireless access, provide access internet access for visitors, while possessing a strong security protection
system at all times.

26

7

4.2.2Wireless security mode WEP

When you select 64-bit or 128-bit WEP key, you have to enter WEP keys to encrypt data. You can
generate the key by yourself. You can enter four WE P keys and select one of them as default key. Then
the access point will just allow the clients that with the same encryption keys connected.

2

4.2.3Wireless security mode WPA PSK/WPA2 PSK

Wi-Fi Protected Access (WPA) is an advanced security standard. You can use a pre-shared key to
authenticate wireless stations and encrypt data during communication. It uses TKIP or CCMP (AES) or
Mixed mode (TKIP+AES) to change the encryption key frequently. So the encryption key is not easy to be
broken by hackers. This can improve security very much.

4.2.4Wireless security mode WPA Radius/WPA2 Radius

You can use a RADIUS server to authenticate wireless stations and provide the session key to encrypt
data during communication. It uses TKIP or CCMP (AES) to change the encryption key frequently.

Chapter 5 Security

5.1 Firewall

VRT-420N provides extensive firewall protection by restricting connection parameters, thus limiting the
risk of hacker attack, and defending against a wide array of common Internet attacks.

Configure Security Settings following the instructions below.

SPI Firewall Protection Select Enable to enable SPI Firewall Protection.

Select Disable to disable SPI Firewall Protection.

TCP SYN DoS Protection Check to enable TCP SYN DoS Protection.

Uncheck to disable TCP SYN DoS Protection.

TCP SYN DoS attack sends a flood of TCP/SYN packets. Each of these packets are like a
connection request, causing the server to consume computing resources (e.g. memory,
CPU) to reply and to continuously wait for the incoming packets. Without TCP SYN Dos
Protection, the resources in the server will be easily consumed completely. This will then
consequently result in the dysfunction of the server.

VRT-420N is able to detect TCP SYN DoS attacks and limits the resource consumption by
lowering the incoming request rate by fast recycling the resource.

ICMP Broadcasting
Protection

Check to enable ICMP Broadcasting Protection.
Uncheck to disable ICMP Broadcasting Protection.

ICMP broadcasting attack is a type of DoS attacks. A flood of ICMP broadcasting packets is
generated and sent to a server. Consequently, this server will suffer from a huge amount of
interruptions and consumption of computing resources.

VRT-420N is able to stop responding to ICMP broadcasting echo packets in order to avoid
a potential ICMP broadcasting DoS attack.

33

ICMP Redirect Protection Check to enab le ICMP Redirect Protection.

Uncheck to disable ICMP Redirect Protection.

An ICMP redirect message is a way to change the existing routing path. Generally, ICMP
redirect packets should not be sent, and so when there is the occurrence that ICMP
redirect packets are sent, it is important to note that it is very likely to be used as a means
for a network attack.

Broadcast Storming Check to enable Broadcast Storming Protection.

Uncheck to disable Broadcast Storming Protection.

A state in which a message that has been Broadcast across a network results in even more
responses, and each response results in still more responses in a snowball effect. A severe
broadcast storm can block all other network traffic, resulting in a network meltdown.
Broadcast storms can usually be prevented by carefully configuring a network to block
illegal broadcast messages.

Chapter 6 Application Settings

6.1 Application Settings

The Status screen allows you to monitor the current status of your router. You can use the
Status page to monitor the connection status of Applications Settings.

By activating the port range forwarding function, remote users can access the local network
via the public IP address. Users can assign a specific external port range to a local server.
Furthermore, users can specify an internal port range associated in a port range forwarding
rule. When VRT-420N receives an external request to access any one of the configured
external ports, it will redirect the request to the corresponding internal server and change its
destination port to one of the internal ports specified. Therefore, if users do not wish for
destination port to be changed for a request, the internal port range should be left empty.

By enabling DMZ Host Function, you can set up a DMZ host at a particular computer
exposed to the Internet. In this way, some applications, especially online games (if the traffic
port numbers of the applications are always changing), can be easily accessed.

Chapter 10 Troubleshooting

If you found VRT-420N is working improperly or stop responding to you, please kindly read this
troubleshooting first. Some problems can be solved by you within very short time! Please contacts with
your local dealer if below methods are failed.
 Router is not responding to me when I want to access it by web browser.

1. Please check the connection of power cord and network cable of this router. All cords and cables
should be correctly and firmly inserted to the router.

2. If all LEDs on this router are off, please check the status of A/C power adapter, and make sure it’s
correctly powered.

3. You must use the same IP address section which router uses.

4. Are you using MAC or IP address filter? Try to connect the router by another computer and see if it
works; if not, please restore your router to factory default settings (pressing ‘reset’ button for over 10
seconds).

5. Set your computer to obtain an IP address automatically (DHCP), and see if your computer can get
an IP address.

6. If you did a firmware upgrade and this happens, contact your dealer of purchas e for help.

 Why I can’t get connected to Internet?

1. Call your Internet service provide and check if there’s something wrong with their service.

2. If you just can’t connect to one or more website, but you can still use other internet services, please
check URL/Keyword filter.

3. Try to reset the router and try again later.

4. Reset the device provided by your Internet service pr ovider too.

5. Try to use IP address instead of hostname. If you can use IP address to communicate with a remote
server, but can’t use hostname, please check DNS setting.

 Why I can’t locate my router by my wireless client?

1. ‘Broadcast ESSID’ set to off?

2. All two antennas are properly secured.

3. Are you too far from your router? Try to get closer.

4. Please remember that you have to input ESSID on your wireless client manually, if ESSID broadcast
is disabled.

 File download is very slow or breaks frequently

1. Are you using QoS function? Try to disable it and try again.

2. Internet is slow sometimes, being patient.

3. Try to reset the router and see if it’s better after that.

68

4. Try to know what computers do on your local network. If someone’s transferring big files, other
people will think Internet is really slow.

5. If this never happens before, call you Internet service provid er to know if there is something wrong
with their network.

 I can’t log onto web management interface: password is wrong

1. Make sure you’re connecting to the correct IP address of the router!

2. Password is case-sensitive. Make sure the ‘Caps Lock’ light is not illuminated.

3. If you really forget the password, do a hard reset.

 Router become hot

1. This is not a malfunction if you can keep your hand on the router’s case.

2. If you smell something wrong or see the smoke coming out from router or A/C power adapter, please
disconnect the router and A/C power adapter from utility power (make sure it’s safe before you’re
doing this!), and call your dealer of purchase for help.

 The date and time of all event logs are wrong

1. Adjust the internal clock of router.
