How to configure port mapping on Reyee EG?

1. Getting Started

• Confirm the intranet IP address of the mapping device on the LAN and theport number used by the service.
• Confirm that the mapped service can be normally used on the LAN.
  

2. Configuration Steps
Choose One-Device > Gateway >Config >Advanced> Port Mapping > PortMapping.
Click Add. In the dialog box that appears, enter the rule name, service type, protocoltype, external port/range, internal server IP address, and internal port/range.You can create a maximum of 50 port mapping rules.



Table 1-1 Port mapping configuration

Parameter	Description
Name	Enter  the description of the port mapping rule, which is used to identify the rule.
Preferred  Server	Select  the type of service to be mapped, such as HTTP or FTP. The internal port  number commonly used by the service is automatically entered. If you are not  sure about the service type, select Custom.
Protocol	Select  the transmission layer protocol type used by the service, such as TCP or UDP. The value ALL  indicates that the rule applies to both protocols. The value must comply with  the client configuration of the service.
External  IP Address	Specify the host address used for  accessing the external network. You can set it to the following:  l Outbound Interface: You can select All WAN  Ports or specify a WAN port.  l Enter or select an IP address: Select or enter the IP  address of a WAN port.
External  Port/Range	Specify  the port number used for Internet access. You need to confirm the port number  in the client software, such as the camera monitoring software. You can enter  a port number or a port range, such as 1050-1060. If you enter a port range,  the value of Internal Port/Range  must also be a port range.
Internal  IP Address	Specify  the IP address of the internal server to be mapped to the WAN port, that is,  the IP address of the LAN device that provides Internet access, such as the  IP address of the network camera.
Internal  Port/Range	Specify  the service port number of the internal server to be mapped to the WAN port,  that is, the port number of the application that provides Internet access,  such as port 8080 of the Web service.   You  can enter a port number or a port range, such as 1050-1060. If you enter a  port range, the number of ports must be the same as that specified in External Port/Range.

3. Verification and Test
Check whether the external network device canaccess services on the destination host using the external IP address and external port number.
4. Solution toTest Failure
(1) Modify the value of ExternalPort/Range and use the new external port number to perform the test again.The possible cause is that the port is blocked by the firewall.
(2) Enable the remote access permission on the server. The possible cause isthat remote access is displayed on the server, resulting in normal internal access but abnormal access across network segments.
(3)Configure DMZ rules. For details, see community.ruijienetworks.com/forum.php?mod=viewthread&tid=7940&page=1&extra=#pid15929 . The possible cause is that the specified ports are incorrect or incomplete.
