Type, tap the spacebar once, and then type the address of a website you want to block. For example, to block all traffic from YouTube, type on this line. 5. Continue to add the websites you wish to block, each prefaced with and a space.
Hop into your PTCL broadband router by typin' this in the URL bar Or You might have a different IP address whatever it is. After typin', the IP address somethin' would pop up askin' for the username and password enter them. If you don't know yours. The username and password are written on the down of Broadband. When you are logged in. There would be a table shown on the left of your screen. Go to >Advance Setup >Parental Control >Url Filter Click on Exclude if it's showin' in there Or just click on Add then put the website URL you are wantin' to block and the port is 80 always. and check all the days to block it permanently. click apply/save and you're done.
