Networking issues
Thanks to its robust security the Wizard IP Plus offers you great flexibility in how
it integrates into an existing network structure. The Wizard IP Plus is designed
to reside either on an internal network, behind a firewall/router or alternatively
with its own direct Internet connection.
Positioning Wizard IP Plus in the network
Every network setup is different and great care needs to be taken when
introducing a powerful device such as the Wizard IP Plus into an existing
configuration. A common cause of potential problems can be in clashes with
firewall configurations. For this reason the Wizard IP Plus is designed to be
intelligent, flexible and secure. With the minimum of effort the Wizard IP Plus
can reside either behind the firewall or alongside with its own separate Internet
connection.
Placing Wizard IP Plus behind a router or firewall
A possible point of contention between the Wizard IP Plus and a firewall can
occasionally arise over the use of IP ports. Every port through the firewall represents
a potential point of attack from outside and so it is advisable to minimise the number
of open ports. The Wizard IP Plus usually uses two separate port numbers, however,
these are easily changeable and can even be combined into a single port.
IMPORTANT: The correct configuration of routers and firewalls requires advanced
networking skills and intimate knowledge of the particular network. Black Box cannot
provide specific advice on how to configure your network devices and strongly
recommend that such tasks are carried out by a qualified professional.
Port settings
As standard, the Wizard IP Plus uses two ports to support its two types of viewer:
•
Port 80 for users making contact with a web browser, and
•
Port 5900 for those using the VNC viewer.
When these port numbers are used, VNC viewers and web browsers will locate
the Wizard IP Plus correctly using only its network address. The firewall/router
must be informed to transfer traffic, requesting these port numbers, through to
the Wizard IP Plus.
When a web server is also on the local network
Port 80 is the standard port used by web (HTTP) servers. If the Wizard IP Plus is situated
within a local network that also includes a web server or any other device serving port
80 then, if you want to use the web browser interface from outside the local network
environment, the HTTP port number of the Wizard IP Plus must be changed.
When you change the HTTP port to anything other than 80, then each remote
browser user will need to specify the port address as well as the IP address. For
instance, if you set the HTTP port to ‘8000’ and the IP address is ‘192.168.47.10’
then browser users will need to enter:
http://192.168.47.10:8000
(Note the single colon that separates the IP address and the port number).
The firewall/router would also need to be informed to transfer all traffic to the
new port number through to the Wizard IP Plus.
If you need to change the VNC port number
If you change the VNC port to anything other than 5900, then each VNC viewer
user will need to specify the port address as well as the IP address. For instance,
if you set the VNC port to ‘11590’ and the IP address is ‘192.168.47.10’ then
VNC viewer users will need to enter:
192.168.47.10::11590
(Note the double colons that separate the IP address and port number).
The firewall/router would also need to be informed to transfer all traffic to the
new port number through to the Wizard IP Plus.
