What Ports need to be open for LAN and WAN Access for Divar AN 3000/5000?
Answer
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.
The HTTP port is 80, and the TCP port is 37777, by default (configurable)
- The allowed port ranges are shown beside each connection type.

🛈 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. |

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