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.
•
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)

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
