E.2 Placing Wizard DXS - Digital behind a router or firewall
A possible point of contention between the Wizard DXS - Digital 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 DXS - Digital 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 DXS - Digital 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 DXS - Digital correctly using only its
network address. The firewall/router must be informed to transfer traffic, requesting these port numbers, through to the Wizard
DXS - Digital.
When a web server is also on the local network
Port 80 is the standard port used by web (HTTP) servers. If the Wizard DXS - Digital 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 DXS - Digital 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 DXS -
Digital.
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 DXS -
Digital.
