procedure. The results will be displayed in the Ping Results pane.

tempts from the Internet.
Current
IP Address
This is the current address you will use when accessing this device
from the Internet. To connect, see details and an example below.
Port Number
Enter a port number between 1 and 65535. The default for HTTP
(Web) connections is port 80, but using port 80 will prevent the use
of a Web "Virtual Server" on your LAN. So using a different port
number is recommended. The default value is 8080.
The port number must be specified in your Browser when you
connect. See the following section for details.
Access Permission
Allow Remote
Access
Select the desired option.
• Everyone - allow access by everyone on the Internet.
• Only This Computer - allow access by only one IP address.
Enter the desired IP address.
• IP Address Range - allow access from a range of IP addresses
on the Internet. Enter a beginning and ending IP address to de-
fine the allowed range.
For security, you should restrict access to as few external IP ad-
dresses as practical.
