Go to Access Control-Host,then click “Add New…”
In this example,the router TL-WR1043’s LAN IP address is 192.168.1.1,IP Range is 192.168.1.100~126.96.36.199.We are going to set up rules to block google all the time on all the devices in the network,but no restriction to any other websites.
Click "Save" - the new Host rule will now show up on the "Host Settings" page
Step 3: Go to Access Control -> Target, then click "Add New..."
Select "Domain Name" in the "Mode:" box, then enter a brief description of the rule you are setting up. In the "Domain Name:" box(es), enter the keywords you would like the router to block (these do not have to be full web addresses such as www.google.com - simply entering "google" will set the rule to block ANY domain name that contains the word "google")
Click "Save" - the new Target rule will now show up on the "Target Settings" page
Step 4: Go to Access Control -> Rule page and tick "Enable Internet Access Control", then select the option " Deny the packets specified by any enabled access control policy to pass through the Router" (if this is set to the "Allow" option, all websites other than ones you have set Host/Target rules for will be blocked), then click "Save".
Under Access Control -> Rule, click "Add New...", then enter a brief description of the rule in the "Rule Name:" box
In the "Host:" box, select the Host rule you defined in Step 2
In the "Target:" box, select the target rule you defined in Step 3
In the "Schedule:" box, select "Anytime" (this will make the rule always active)
In the "Action:" box, select "Deny"
In the "Status:" box, select "Enabled"
Click "Save" - the new Access Control rule will now show up on the "Access Control Rule Management" page .
Step 5: To test the rule, try to browse to the site you have blocked from a host PC in the IP address range you defined in the Host rule in Step 1 (for instance, http://www.google.com ). The website will be blocked, and your web browser will report that the site/server cannot be found.
