![]() The technician might then need to install a separate Router behind the Modem, hence creating the Nested Configuration outlined above. This most often disables the devices Routing features. * In this situation, it is often required to have the Internet Service Provider configure your combination Router/Modem as a pure Modem in order to enable Bridged Mode. You can be relatively sure that this scenario is in play if you are 100% certain that the Router/Modem Port Forwarding is correct, but the ports simply will not open. Sometimes, with these devices, the Modem feature(s) prevent the ports from successfully forwarding through the devices’ own Firewall. * The routing device is a single combination Router/Modem. [The modem will possibly need to be configured for ‘Bridged Mode’. * The routing device to which the recorder is connected is non-internet-facing, and is connected to an internet-facing Modem. This type of environment is likely ‘managed’ by an IT/Network Administrator or similar entity. * There are multiple routing devices in play and the recorder is directly connected to a ‘non-internet-facing’ routing device. A nested configuration exists under the following conditions… Below are a couple of example/scenarios where you might run into problems getting Ports Forwarded through a firewall… In regard to Port Forwarding in general, even the most experienced technician can run into trouble. If you do not find your routing devices’ Port Forwarding walkthrough in the ‘List of all Routers’ available on often you can often find a walkthrough for earlier/later models from the same manufacturer that are similar enough to the unit upon which you are working to assist in getting the job done. When encountering an environment where Port Forwarding is required, and the installer is unfamiliar with the process, the routing hardware, etc, a good reference to use is This site has detailed walkthroughs for hundreds of current and legacy routing devices. Fortunately, there are an abundance of informational resources available to assist with Port Forwarding. That said, with the proliferation of commercial/residential intranet/internet technology today, it’s often left up to vendors, and even the residents/business owners themselves, to perform any required Port Forwarding operation(s). The actual task of Forwarding Ports through a firewall should always be performed by an experienced IT professional. Your networking environment provides internet access. Your recorder has already received an IPv4 address that starts with .x, 10.x.x.x, 172.16.x.x, 172.32.x.x via static assignment…ĭ. Your recorder has already received an IPv4 address that starts with .x, 10.x.x.x, 172.16.x.x, 172.32.x.x via DHCP. Your recorder is behind a firewall often provided by your local routing device. In order for Port Forwarding to be successful, the following basic requirements must be met:Ī. This IPv4 address is the address to which you will be forwarding your ports. In most instances, your local IT/Network Administrator will provide a private IPv4 address for the recorder. This will assign the DHCP-issued IPv4 address statically. In some instances, you can allow the local DHCP server to assign the recorder an IPv4 address, then disable DHCP on the recorder. Port assignments ‘can’ be changed to accommodate ISP port restrictions and/or rules as defined by your network administrator, etc. The above are examples of default port assignments. The Port values most often Forwarded (pre-defined) on current Hunt Electronic recorder models are … Please review this document in its entirety before calling Hunt Electronic Technical Support for assistance with Port Forwarding. This document is intended as a ‘guide’ for technicians who are in need of basic assistance with Port Forwarding, and contains reference to external resources. In many instances, Port Forwarding is required to provide remote access to Hunt Electronic recorder features and functions.ĭue to the diversity of networking environment, difference in routing-device make, model, function and features, as well as a host of other topological and environmental factors, a single definitive Port Forwarding document is not currently available for technical reference.
