Binding

•

Bind WAN port/Session

– Select

Enable

if you wish to associate this PC with

a particular PPPoE Session. All traffic for that PC will then use the selected

PPPoE port and session.

•

Binding Method

– Suppose your PC is bound to WAN1 port, now you are

selecting “Strict Binding”. If WAN1 port is disconnected, your packets cannot

go out through WAN2 port, if WAN2 port is still alive. If you are selecting

“Loose Binding” then when WAN1 port is disconnected, your packets will

automatically go to WAN2, if WAN2 is alive.

•

Select WAN Port/Select PPPoE session

– If the setting above is

Enable

,

select the desired Port and Session. Otherwise, ignore these settings.

Note

: Multiple PPPoE sessions are defined on the

Advanced PPPoE

screen.

Virtual Servers

This feature allows you to make Servers on your LAN accessible to Internet users. Normally, Internet

users would not be able to access a server on your LAN because:

•

Your Server's IP address is only valid on your LAN, not on the Internet.

•

Attempts to connect to devices on your LAN are blocked by the firewall in the

Load Balancer.

The "Virtual Server" feature solves these problems and allows Internet users to connect to your

servers, as illustrated below.

Figure 14: Virtual Servers

Note that, in this illustration, both Internet users are connecting to the same IP Address, but using

different protocols.

Connecting to the Virtual Servers

Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the

Load Balancer's Internet IP Address (the IP Address allocated by your ISP).

e.g.

http://205.20.45.34

ftp://205.20.45.34

•

To Internet users, all virtual Servers on your LAN have the same IP Address. This IP Address is

allocated by your ISP.

•

This address should be static, rather than dynamic, to make it easier for Internet users to connect

to your Servers. However, you can use the

Dynamic DNS

feature (explained later in this chapter)

28

HotBrick Network Solutions

to allow users to connect to your Virtual Servers using a URL, instead of an IP Address.

e.g.

HTTP://my_domain_name.dyndns.org

FTP://my_domain_name.dyndns.org
