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.

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
