Whether EW1800 supports port forwarding?

a) Overview

Port mapping maps theIP address of a device on the LAN to an external network in the form of acombination of a WAN IP address and a port number, so as to provide theexternal network access service.

1) Scenario 1: Whenyou need to access IP cameras or PCs at home while you are away from home, portmapping needs to be configured.

2) Scenario 2: When aserver needs to be set up on the home network for Internet access, port mappingor demilitarized zone (DMZ) needs to be configured.

Port mapping maps theWAN port IP address of a router to an internal network host and port so thatInternet users can proactively access hosts on the LAN.

DMZ forwards allpackets from the Internet to DMZ hosts to provide the Internet access service.

b) Getting Started

1) Confirm the IPaddress of the target device in the internal network and service port ID.

2) Ensure that portmapping is available in the internal network.

c) Configuration Steps

Choose More > Advanced > Port Mapping.

Yes,it supports port mapping/port forwarding.
The configuration steps are as follows



Click Add. In the pop-up dialog box, enterthe name, service type, protocol type, external port/range, internal IPaddress, and internal port/range. A maximum of 50 port mapping rules can beconfigured.

Name: Enter a name for easy maintenance.
Preferred Server: Select a service to bemapped, such as HTTP or FTP. The device will automatically fill in the internalport number of the service. If you are not sure of the service, you can selectCustom.
Protocol: Select the transport-layerprotocol used by the selected service, such as ALL, TCP, or UDP. Theconfiguration on the server end must be consistent with that on the client end.
External Port/Range: Enter the portnumber used for external network access. You need to check the port number insoftware, such as camera monitoring software.
Internal IP Address: Enter the LAN IPaddress used by external networks to access the device, such as the IP addressof an IP camera.
Internal Port/Range: Enter the portnumber used by an application accessed by external networks, such as port 8080used by the Web service.
d) Verification and Testing
Use an external deviceto test whether the destination service is accessible based on the external IPaddress and port number.
e) Solution to a Test Failure
1) Use a new externalport number and perform the test again. The test often fails on the portsblocked by firewalls of some ISPs.
2) Enable the remoteaccess permission on the server. The common cause is that remote access is disabledon the server by default. As a result, the internal network access issuccessful but the access across different network segments is failed.
