Your server in the intranet, please do port mapping on the router, you can normal use!

Please open 6601-6612 (TCP/UDP), 2121(TCP), 2122-2162(TCP), 6617-6622(TCP), 6630-6635(TCP), 88(TCP), total 67 ports!

For example, Huawei routers.

Port mapping allows you to map a port on your router’s WAN IP address to a computer within a LAN. When you use the Internet to access a specific port on the WAN IP address (for example, in order to access a webcam on a home network), the router will check the port value against the port mapping rules, then map your service request to the specific port on the local IP of the computer.

To configure port mapping rules:

1. Connect your computer to the router’s Wi-Fi (or connect the computer to the router’s LAN port using an Ethernet cable). Enter the default IP address in your browser address bar and log in to the web-based management page(check the nameplate at the bottom of the router for the default IP address). For routers that feature self-adaptive ports, you do not need to distinguish between WAN and LAN ports.

2．Go to More Functions > Security Settings > NAT Services and click the icon in the upper right corner of Port Forwarding to add a new port mapping service.

In Service name, enter a custom name for the port mapping service. In Device name, select the computer resource that you want to configure port mapping for (such as a Web server or FTP server). In Protocol, select the port mapping protocol you want to use. In Internal Port, enter the service port number of the computer that provides external service. In External Port, enter the router’s service port number for Internet user access. Click Saveto save your configuration.
