If you cannot set your modem to Bridging mode, then you need to bypass the router. Typically this
is done by plugging the computer directly into the back of the modem. If there are not enough jacks
to plug the computer directly into the modem, use a hub or switch to increase the number of jacks
present. Run a cable from the modem into a hub, then run a cable from the hub to your computer. If
you still need the router then you can also plug the router into the hub—just do not plug the DVR into
the router. Now that the router has been bypassed, set up port forwarding on the modem, as detailed
in 3.40.7 Setting up Port Forwarding on Pg. 93.

3.40.7 Setting up Port Forwarding
Your router must be configured for Port Forwarding in order for a user to view your DVR from a remote
location. If there are many computers within a network, a router is used to help split the connection
to the internet. If a router does not know which PC is the recipient of a connection request, the router
discards the request. Port Forwarding forces a router to send the connection request to a specific
computer—in our case, the DVR.
3.40.7.1 Business Connections
If you have a business internet connection, you will want to contact your ISP and determine if they
must set up the Port Forwarding for you. Many business connections use special modems that cannot
be configured by the user. If this is the case, you must contact your ISP and ask them to set up port
forwarding on the following ports: Port 80 (if Port 80 cannot be used, we recommend port 8000), Port
5140, Port 5150, and Port 5160.
► Note It is not enough merely to 'Open' a port. If a port is 'Open,' then your
connection request will not be blocked, but forwarding is STILL required to
tell the router which computer to send the connection request. Many ISPs
may misunderstand this and only 'Open' the port, and because forwarding
is not set up, you still will be unable to connect. Please make certain the ISP
has actually forwarded, and not just opened, your ports.
