C.4

Inbound Access Restriction

C.4.1 Scenario

A firewall is required in order to protect the network from potential hacker attacks and other Internet

security threats.

C.4.2 Solution

Firewall functionality is built into the Peplink Balance. By default, inbound access is unrestricted. Enabling

a basic level of protection involves setting up firewall rules.

For example, in order to protect your private network from external access, you can set up a firewall rule

between the Internet and your private network. To do so, navigate to

Network>Access Rules

. Then click

the

Add Rule

button in the

Inbound Firewall Rules

table and change the settings according to the

following screenshot:

After the fields have been entered as in the screenshot, click

Save

to add the rule.

Afterwards, change the default inbound rule to

Deny

by clicking the

default

rule in the

Inbound Firewall

Rules

table. Click

Apply Changes

on the top right corner to complete the process.

C.5

Outbound Access Restriction

C.5.1 Scenario

For security reasons, it may be appropriate to restrict outbound access. For example, you may want to

prevent LAN users from using ftp to transfer files to and from the Internet.

This can easily be achieved by setting up an outbound firewall rule with Peplink Balance.

C.5.2 Solution

To setup a firewall between Internet and private network for outbound access, navigate to

Network>Access Rules

. Afterwards, click the

Add Rule

button in the

Outbound Firewall Rules

table,

and then follow the settings according the screenshot:

After the fields have been entered as in the screenshot, click

Save

to add the rule. Click

Apply Changes

on the top right corner to complete the process.

Appendix D. Troubleshooting

Problem 1

Outbound load is only distributed over one WAN connection.

Solution

Outbound load balancing can only be distribute traffic evenly between available WAN connections if many

outbound connections are made. If there is only one user on the LAN and only one download session is

made from his/her browser, the WAN connections cannot be fully utilized.

For a single user, download management applications are recommended. The applications can split a file

into pieces and download the pieces simultaneously. Examples include: DownThemAll(Firefox Extension),

iGetter (Mac), etc.

If the outbound traffic is going across the SpeedFusion

TM

tunnel, (i.e. transferring a file to a VPN peer)the

bandwidth of all WAN connections will be bonded. In this case, all bandwidth will be utilized and a file will

be transferred across all available WAN connections.

For additional details, please refer to this FAQ:

http://www.peplink.com/knowledgebase/maximizing-your-wan-connections-without-speedfusion/

Problem 2

I am using a download manager program (e.g. Download Accelerator Plus, DownThemAll etc.) now.

Why

is the download speed still only that of a single link?

Solution

First, check whether all WAN connections are up.

Second, ensure your download manager application has split the file into 3 parts or more.

It is also possible that all of 2 or even 3 download sessions were being distributed to the same link by

chance.

Problem 3

I am using some websites to lookup my public IP address, e.g.

www.whatismyip.com

.WhenIkeep

pressing the browser's Refresh button, the server almost always returns the same address. The IP

address supposed to be changing for every refresh

Solution

The web server has enabled the

Keep Alive

function, which ensures that you use the same TCP session

to query the server.

Try to test with a web site that does not enable

Keep Alive

.

For example, try

http://private.dnsstuff.com/tools/aboutyou.ch

(This third-party web site is provided only for

availability.)

Problem 4

What can I do if I suspect a problem on my LAN connection?

Solution

You can test the LAN connection using

Ping

.

For example, if you are using DOS/Windows, at the Command Prompt, type:

ping 192.168.1.1

This pings the Peplink Balance device (provided that Peplink

Balance device’s IP is 192.168.1.1) to test

whether the connection to Peplink Balance is OK.

Problem 5

What can I do if I suspect a problem on my Internet/WAN connection?

Solution

You can test the WAN connection by

Ping

, which is similar to problem 4.

As we want to isolate the problems from the LAN,

Ping

will be performed from Peplink Balance. By using

the

Ping

/

Traceroute

under the tab

Status

of the Peplink Balance, you may able to find out the source of

problem.

Problem 6

When I upload files to a server via ftp, the transfer stalls after a few kilobytes of data are sent. What

should I do?

Solution

The Maximum Transmission Unit (MTU) or MSS setting may need to be adjusted.

By default, the MTU is set at 1440. Choose

Auto

for all of your WAN connections. If that does not solve

the problem, you can try the MTU 1492 if a connection is a DSL. If problem still persists, change the size

to progressive smaller values until your problem is resolved (e.g. 1462, 1440, 1420, 1400, etc).
