MAC Filter

The MAC Filter is a powerful security feature that allows you to specify which

computers are allowed on the network. Wireless connections to the AirStation

can be limited to speciﬁc client MAC addresses to enhance security against

unwanted network visitors. When enabled, only wireless client adapters with

registered MAC addresses will be allowed to connect to the AirStation.

Note: The wireless MAC ﬁlter is ignored while AOSS is in use.

Check “

Enable”

to use MAC ﬁltering.

Click the “

Registration List

” button to display the MAC Address Filter List. To

put a device on the list, you must know its Medium Access Control (MAC)

address, often called its MAC or LAN MAC. This normally can be found on a

label on the bottom or back of the device, or on the network interface card in

a desktop computer.

When the desired MAC addresses are entered, click “

”to save the list.

Security

Firewall

Page 22 / 39

Limits the type of packets allowed to pass between the Internet and LAN.

When packets reach the AirStation, the ﬁrewall evaluates the packets, and

forwards packets that don’t match any ﬁlter to their destination. The Firewall

blocks unnecessary packets from the Internet side and prevents leaking

secure information from the LAN side.

Prohibit NBT and Microsoft-DS routing

Prevents unexpected external access via Microsoft network sharing. The

default setting is disabled.

Reject IDENT requests

When this is enabled, the AirStation sends reject packets if it receives an

IDENT request. The default setting is enabled. Use this ﬁlter when the com

munication speed goes down using a network application like e-mail, ftp or

WEB. If IDENT requests are forwarded to a LAN side client by address transla

tion setting (DMZ or TCP port:113), this basic rule is ignored.

Block Ping from Internet

An anonymous Internet request is an attempt to ping your broadband gate

way’s WAN interface. Pinging is a way of checking if a system is running at a

particular IP address. It can also be used to hunt for certain kinds of vulner

abilities in the system. Blocking WAN requests means not responding to pings

coming from the Internet. This is the default setting.

IP Filter Settings

Page 23 / 39

Limits the type of packets allowed to pass between the Internet and LAN. The

maximum number of rules is 32.

If the packet meets one of the monitoring conditions before it is routed, the

speciﬁed action will be taken. If multiple conditions are met, the appropriate

action will be performed once the packet meets the condition.

VPN Pass Through

PPPoE Pass Through

This setting enables an rfc1483 bridge mode in the modem so the PPPoE

process occurs in the connected device, eg a ﬁrewall router or PC.

PPTP Pass Through

PPTP is a tunneling protocol deﬁned by the PPTP forum that allows PPP pack-

ets to be encapsulated within Internet Protocol (IP) packets and forwarded

over any IP network, including the Internet itself. PPTP ensures that messages

are transmitted from one private network to another.

LAN Conﬁg

Port Forwarding

Page 24 / 39

Port Forwarding allows you to route external (Internet) calls for services such

as a web server (port 80), FTP server (Port 21), or other applications, through

your Router to your internal network. Since your internal computers are pro-

tected by a ﬁrewall, machines from the Internet cannot get to them because

they cannot be‘seen’. If you need to conﬁgure the port forwarding function

for a speciﬁc application, you will need to contact the application vendor

to ﬁnd out which port settings you need. You can manually input this port

information into the Router.

DMZ

If you have a client PC that cannot run an Internet application properly from

behind the ﬁrewall, you can open the client up to unrestricted two-way Inter-

net access. This may be necessary if the NAT feature is causing problems with

an application such as a game or video conferencing application. Use this

feature on a temporary basis as a DMZ host is highly exposed to the dangers

of the Internet

To put a computer in the DMZ, enter its LAN IP address and click “

Apply

” for

the change to take eﬀect.

UPnP

Setting up the internet gateway function of UPnP: On a PC which supports

UPnP (Windows XP, etc.), the AirStation is automatically recognized on the

LAN as an internet gateway. Also, if a network application which supports

UPnP is used, it can acquire the Internet port status of the AirStation and

the Internet IP address obtained from your ISP, and perform port translation

automatically.

QoS

Quality of Service (QoS) assigns priority levels to diﬀerent kinds of packets

to minimize delays in the transfer of data. The table lists four common ap

plications and lets you enter the port numbers for up to four more. Click the

High Priority button for the application(s) whose packets you wish to receive

preferential treatment.

Admin Conﬁg

Name

This can be used to assign a speciﬁc descriptive name for the AirStation.

The AirStation name may be up to 64 alphanumeric characters in length, and

’-’ are allowed, but a ’-’ may not be the ﬁrst or last character in the name. By

default, the AirStation name is its LAN-side MAC address. This name is used

as the host name for the Internet side DHCP server when the DHCP client is

enabled.

When log information to the syslog server is transmitted, it uses it as the host

name.

Password

Conﬁgure the Administrator Password to review the AirStation settings.

Change your root password here. Password may use alphanumeric characters

and underscores‘_’, and may be up to 8 characters long.

The default username is the word root and this setting cannot be changed.

Time/Date

You may set the AirStation’s date and time manually or acquire this informa

tion from your PC (The Time Zone cannot be acquired by this method)

NTP

If an NTP server is conﬁgured, the AirStation will access the speciﬁed NTP

server and adjust it’s internal clock to conform with the NTP server’s time. NTP
