Port Forwarding - Swann DVR4-1200 User Manual

Port Forwarding

Port Configuration
If you're not using UPnP, then you'll need to manually forward ports from your
router to your DVR.
Why?
The DVR4-1200 needs two "ports" to be available and properly configured (using
either UPnP or manually forwarding ports ) to work correctly over the Internet. One
of these is called the "Media Port" and the other is called the "Web Port".
These "ports" are like a pin-hole in your network's security screen (tech people
call this security a "firewall") which allows devices to send and receive data from
devices on your network. If there's no hole, devices can't talk to each other. If the
hole is too big, then it presents a security risk. Opening a few, carefully selected
ports and assigning them to specific devices strikes the most useful balance
between these two extremes.
Media Port: The default value is "9000".
Web Port: The default value is "80" - we strongly suggest changing this as "80"
is a port frequently used by various programs (in fact, it's the default HTTP port).
Generally, "85" or "3100" are better choices - however, you can set this to be
anything that you want, just be sure to remember it! You'll need it later.
Remember: If you're not using UPnP (some older routers do not support it) then
you'll need to forward these ports, which involves configuring your router. Check
out www.portforward.com for guides on how to do this.
If you are using UPnP, you won't need to forward ports.
We think that UPnP is the way to go, if your router supports it.
