by a forward slash like this:

so that the browser
won’t default to a DNS search. Using the Hostname obviates
having to check the IP address before connecting, and unique
names can help identify and manage multiple 525Ns on a net-
work.
The
HTTP Port:
has a default value of 80. This is a common as-
signment, but one reason it might need to change is if you
have more than one 525N on your network. Your IT depart-
ment will know all about this and what to do.
ACCESSING THE 525N REMOTELY
On a common Local Area Network (LAN), we already have ac-
cessed the 525N Web interface by entering its IP address or,
under Windows, its Hostname (plus /) into your browser’s ad-
dress bar.
To address the 525N from outside your LAN (from the Inter-
net), the unit needs to have a static IP address. If your router
makes DHCP assignments for other equipment on the network,
simply assign the 525N a static IP that is outside the router’s
DHCP range. This should be an easy matter with the aid of the
router’s Help utility (let your IT department help here).
You also need to open a specific port for the 525N on the net-
work router. Within the router’s Port Forwarding utility you
will be able to enter your static IP address for the unit (Internal
IP), followed by a colon and a port number. The default port
number for the 525N is 80, but as we pointed out earlier it may
be changed to any reasonable number in the router’s range. If
your Internet Service Provider (ISP) assigns you a static IP ad-
dress, then it is a simple matter to address the 525N from any-
where. Just type the IP address and port number into your
browser as shown in this example:
http://55.76.38.170:2345
But if your ISP issues you a dynamic IP, this mandates ‘Dynamic
DNS’ operation utilizing the services of an IP-forwarding pro-
vider.
Dynamic DNS
It would not be possible to address equipment behind a dy-
namic IP address if it were not for IP-forwarding providers
available on the Internet. Their services, which are either free
or at a very modest cost, will allow the 525N to keep the pro-
vider apprised of its reassigned IP address each time that ad-
dress is updated by the ISP. The IP-forwarding provider inter-
cepts data attempting to connect with the 525N and converts
the IP address to the updated one.
Three popular forwarding service providers have been includ-
ed in the 525N setup routine. Their basic service (all you really
