How to open the ports of a TP-Link router?

Step 1 Open the web browser window, enter the IP address of the router into the address field (default value is 192.168.1.1). Then press the Enter key.

Step 2 To log in to the device's configuration page, enter the user name and password (the default value of both fields is: admin).

Step 3 From the left-hand menu select Forwarding->Virtual Servers and then press the Add New... button. .

Step 4 Enter the port number in the Service port field. In the IP Address field, enter the IP address of your computer. Select TCP, UDP or ALL from the Protocol drop-down list. Change the Status field to Enabled

Step 5 To save the settings, press the Save button.

Attention, please:

2. what is DoS protection and how to configure it?

DoS attacks (Denial-of-Service attacks) are cyber attacks that prevent users from accessing network resources and services, usually by flooding the target with large amounts of fake traffic. Typical symptoms are

1) Extremely low network performance;

2 ) Lack of ability to open a specific website;

3 ) Lack of possibility to access websites;

4 ) Unusual increase in the number of spam messages.

DoS protection can protect your network from DoS attacks by monitoring the number of traffic packets. TP-Link routers provide three methods of filtering attacks in DoS protection: ICMP-Flood, UDP-Flood and TCP-Flood.

Do the following, here as the Archer C3150 demonstration:

1. log in to the network interface of the TP-Link router

2 Go to Advanced > System Tools > System Parameters to set the threshold value. Click Save .

3. go to Advanced > Security > Settings to enable DoS Protection.

4. Select the threshold level (Off, Low, Medium or High) for the filtering methods from the drop-down list. Click Save .

1. Filtering of ICMP-FLOOD attacks: Enable it to prevent an ICMP (Internet Control Message Protocol) Flood-type attack.

2. Filtering of UDP-FlOOD attacks: Enable to prevent UDP (User Datagram Protocol) type attacks.

3. Filtering of TCP-FLOOD attacks: Enable to prevent a TCP-FLOOD attack (transmission control protocol).

When the number of packets exceeds the set threshold value, DoS protection will be activated immediately. The faulty host will be displayed in the list of blocked DoS hosts.

Note: If you find that some client devices cannot suddenly access the Internet and have been added to the list of blocked Dos hosts, you should carefully check and monitor the network activity of these client devices. You can set the Dos Protection threshold and lower threshold level when you notice that some specific client devices that do not have any harmful behavior on the Internet are often added to the blocked list.
