SMTP (Simple Mail Transport Protocol) Binding

Unless you are using E-mail accounts from different ISPs on each port, you can

ignore these settings.

Some ISPs configure their E-mail Servers so they will not accept E-mail from IP

addresses not allocated by themselves. If you are using accounts from different

ISPs, sending E-mail over the wrong port may result in non-acceptance of the

mail. In this case, you can use these settings to correct the problem.

•

Enable

- If enabled, the port you specify below will be used for all outgoing

SMTP traffic. If not enabled, either port will be used.

•

WAN 1 / WAN 2

– Select the desired port.

•

Source IP

•

Destination IP

– IP address of destination which packets are sent to.

•

Subnet Mask

– With subnet mask other than 255.255.255.255, you can

make a IP sub-network as your destination.

•

Protocol

- Select the protocol used by the traffic you wish to configure.

•

Port Range

Using Remote Web-based Setup

To connect to the

Load Balancer from a remote PC via the Internet:

1.

Ensure that both your PC and the Load Balancer are connected to the Internet.

2. Start your Web Browser.

3.

In the "Address" bar, enter "HTTP://" followed by the Internet IP Address of the Load Balancer. If

the port number is not 80, the port number is also required. (After the IP Address, enter ":"

followed by the port number.)

e.g.

HTTP://123.123.123.123:8080

•

This example assumes the WAN IP Address is 123.123.123.123, and the port number is 8080.

•

If using the

Dynamic DNS

feature, you can connect using the domain name allocated to you.

e.g.

HTTP://my_domain_name.dyndns.org:8080
