3 Product Description

PePLink Surf, formerly known as MANGA Surf, is a Wi-Fi Station Mode (Client)

Router with WPA, WPA2 and 802.1x supplicant support. It is designed to act

as a Wireless router which connects to Wireless Broadband Internet Service

and allows LAN users to access the Internet via it.

It associates to a service provider and authenticates using 802.1x (if needed)

on start up. Upon successful association and authentication, it will acquire an

IP address from the service provider using DHCP. A DHCP server is built-in

on its LAN port. Network Address Translation is performed for all outbound

connections. Thus it supports multiple terminals to access the Internet

simultaneously.

PePLink Surf User’s Manual v2.6

4.2 Settings Details

LAN Interface: To configure the LAN interface’s IP address and subnet mask.

DHCP Server: To configure to enable the built-in DHCP server or not. If

enabled, the IP address range can be configured.

Wireless Settings:

SSID: To configure the SSID / ESSID / Network Name of the wireless network

to associate to.

Radio Mode: It allows the user to choose between radio modulations support.

E.g. 802.11b/g, 802.11g only, 802.11b, etc. The available settings depend on

the Wi-Fi module installed on the device.

Note: Under 802.11g only mode, 802.11b rates are used during

access point association.

PePLink Surf User’s Manual v2.6

Bit Rate: To fix the 802.11 transmit bit rate. Available options depend on the

Radio Mode chosen. If “auto” is chosen, the device will choose the best bit

rate dynamically and automatically.

Authentication: Available options are Open, Static WEP Key, 802.1x with

dynamic WEP key, WPA/WPA2-Enterprise and WPA/WPA2-Personal. The

selection should be according to the setting of the access point you are

associating to. Data transferred are encrypted under all modes except the

Open mode. When Static WEP Key or WPA/WPA2-Personal is chosen, you

should enter an encryption key in the Encryption Key field. For 802.1x and

WPA/WPA2-Enterprise options, please refer to chapter 4.4 .

Preferred AP: The MAC address of a preferred access point can be entered

here. When the preferred access point is found and its signal strength is

higher than the “Min Signal Strength”, it will connect to this preferred access

point, no matter the other access points are found even they have higher

signal strength or the same SSID.

WAI redirection: If the device is not connected to an access point, and the

user is accessing an Internet web site, the settings control whether to redirect

the web access to the web admin interface page or not. If this is disabled and

the device is not connected, the browser will then show web access error.

The user can still access the web admin interface by accessing to the device’s

LAN IP address. By default, it’s http://192.168.20.1 .

4.4 WPA/WPA2 with 802.1x Authentication

The PePLink Surf supports authentication and encryption methods of “802.1x

with dynamic WEP key encryption” and WPA/WPA2-Enterprise. A radius

server can be used to perform authentication based on the IEEE standard

802.1x with EAP-TTLS.

To set it up, you have to configure the PePLink Surf, the access point and a

radius server.

By default, EAP-TTLS/CHAP is used as the EAP authentication method. You

can change this setting in the System Settings page. Please refer to chapter

4.9.3 .

4.4.1 Configure the PePLink Surf

To enable the 802.1x authentication, you can go to the CPE Setup page,

choose “WPA” for the Authentication setting and leave the WEP key setting

empty.

Certificate checking

By default, the PePLink Surf does not verify the radius server’s

certificate. If you would like to check the certificate, you can use a

command-line based FTP client to upload your certificate to the

PePLink Surf.

1. ftp to the PePLink Surf (default IP is 192.168.20.1)

2. Type the login ID and password: “root” and “MSurf000

”

3. cd /etc/1x

4. put root.pem

5. bye

4.4.2 Access Point

Access point set up procedure is different from one brand to the others. Here

are some necessary configuration parameters to be configured in the access

point:

- Enable WPA2 with 802.1x authentication

- Enter the radius server IP address, port number and the secret (for the provided

radius server config mentioned in 4.4.3 , the secret is “testing123”)

4.4.3 Radius Server

The commercial radius server, Radiator, is used in the set up. It is a product

of Open System Consultants Pty Ltd.

Radiator version 3.9 is known to be interoperable. Any version above 3.9

should work too. Just follow the server’s installation guide to install it on a

server.

After installed, you should put the root cert file and server cert file to a directory,

update radiator’s configuration file and the users files.

A demo CA cert file (cacert.pem), a server cert file (server_cert.pem)

and a server key file (/etc/radiator/server_key.pem) are

pre-generated and attached. You can generate them by yourself by following

the instructions in the Appendix. Put the files to the directory

/etc/radiator.

A sample Radiator configuration file is as follows. Save it as radius.cfg

and put it under /etc/radiator.

5 Appendix - Demo CA and Server Certification

Generation Instructions

5.1 Prerequisite

OpenSSL v0.9.7a or above

Note: The illustration below is based on Linux.

5.2 Create your own Certificate Authority (CA)

1. Create a working directory (e.g. ~/demoCA)

mkdir ~/demoCA

chmod 700 ~/demoCA

cd ~/demoCA

mkdir private certs newcerts

echo -n 01 > serial

touch index.txt

2. Create a private key for your CA, for example:

openssl genrsa -des3 -passout pass:democa -out private/cakey.pem 2048

(A CA private key called "cakey.pem" is then created in the directory

"private". This is a 2048bit RSA private key with pass phrase 'democa'.)

3. Create the server certificate for your CA, for example:

openssl req -new -x509 -days 8000 -key private/cakey.pem -passin

pass:democa -out cacert.pem

Then a series of questions will be asked:

You are about to be asked to enter information that will be incorporated

into your certificate request.

PePLink Surf User’s Manual v2.6

What you are about to enter is what is called a Distinguished Name or a

DN.

There are quite a few fields but you can leave some blank

For some fields there will be a default value,

If you enter '.', the field will be left blank.

-----

Country Name (2 letter code) [GB]:US

State or Province Name (full name) [Berkshire]:US

Locality Name (eg, city) [Newbury]:US

Organization Name (eg, company) [My Company Ltd]:

Organizational Unit Name (eg, section) []:

Common Name (eg, your name or your server's hostname) []:demoCA

Email Address []:

(The CA server certificate is now generated in "cacert.pem")

4. In some applications (e.g. Microsoft Windows), DER version of server

certificate is needed:

openssl x509 -outform DER -in cacert.pem -out cacert.der

(The CA server certificate in DER format is now ready in "cacert.der")

5.3 Create a server certificate request from your servers

1. Create your working directory (e.g. ~/myCert)

mkdir ~/myCert

chmod 700 ~/myCert

cd ~/myCert

2. Create the private key of your server, for example:

openssl genrsa -des3 -passout pass:demoserver -out server_key.pem 2048

(The private key for CA called "server_key.pem" is then created.

This is 2048bit RSA private key with pass phrase 'demoserver'.)

PePLink Surf User’s Manual v2.6

3. Create the certificate singing request of your server, for example:

openssl req -new -key server_key.pem -passin pass:demoserver -out

server_req.pem

Then a series of questions will be asked:

You are about to be asked to enter information that will be incorporated

into your certificate request.

What you are about to enter is what is called a Distinguished Name or a
