    What Ports need to be open for LAN and WAN Access for Divar AN 3000/5000

    To access the DIVAR AN 3000/5000 via web browsers or the mobile DIVAR Viewer App the TCP and the HTTP port shown in the DVR setup needs to be open.
     
    • If both ports are not open or forwarded, logon authentication and viewing live video will fail.

    Port Forwarding allows remote computers (for example, computers on the Internet) to connect to a specific computer or service within a private local-area network (LAN).

    In a typical residential network, nodes obtain Internet access through a DSL or cable modem connected to a router or network address translator (NAT/NAPT). Hosts on the private network are connected to an Ethernet switch or communicate via a wireless LAN. The NAT device's external interface is configured with a public IP address. The computers behind the router, on the other hand, are invisible to hosts on the Internet as they each communicate only with a private IP address.

    When configuring port forwarding, the network administrator sets aside one port number on the gateway for the exclusive use of communicating with a service in the private network, located on a specific host. External hosts must know this port number and the address of the gateway to communicate with the network-internal service. Often, the port numbers of well-known Internet services, such as port number 80 for web services (HTTP), are used in port forwarding, so that common Internet services may be implemented on hosts within private networks.

    3800 TCP
    Reserved. This is currently a private debug port used for
    development purposes. This port will be available in future
    releases
    5000 TCP
    Reserved Used in firmware versions 1.x as private protocol port
    for internal communications. In firmware versions 2.x this port
    is configurable (default is 7892)
    7892 TCP
    Reserved Used in firmware versions 2.x as private protocol port
    for internal communications
    37777 TCP
    Private default port for remote connections; 37777 can be
    changed by configuration

    UDP
    RTPdata transfer; used when rtsp connections are created. Each
    new connection creates 2 port assignments (1 sending, 1
    receiving).

    The HTTP port is 80, and the TCP port is 37777, by default (configurable)

    • The allowed port ranges are shown beside each connection type.
