Removes the routing restrictions on dr. com broadband client logon to enable Internet access for multiple machines under one account

The Dr. COM broadband logon client, developed by Beijing city Hotspot information Co., Ltd., is used to manage the verification and billing of many China Netcom broadband lines in the north. Unfortunately, this client does not work normally after passing through a layer of routing. When logging on, the Client Always prompts that the login server cannot be found, and the account binds the MAC address.

In order to allow only one telephone line to allow multiple machines to access the Internet, I analyzed the Dr. COM broadband logon client and found that it broadcast and listen to port 61440 during verification. So I set forwarding rules on the routing end and mapped port 61440. The detailed settings are as follows:

1. Port ing. Set the internal network host IP address of the client to 192.168.1.2.
2. Sets static IP Address Allocation, corresponding to the host of the MAC address bound to the account

After this setup, one account and one machine can verify that multiple machines can access the Internet.
