so please i need help ??

To block website by FQDN you really need to use either L7 Firewall rules or as I see you trying to do, use a web proxy.

Try reading this:http://wiki.mikrotik.com/wiki/Manual:IP/Proxy
Or this: http://wiki.mikrotik.com/wiki/How_To_Block_Facebook

i have tried the this one before and coudent block it maybe i did something wrong

Firewall Filter
Chain : Forward
Protocol : TCP
Port : 80
Content : Facebook
Action : Drop

but i want to try this and i have no idea where i should type the IP of the website

Nslookup www.facebook.com

Name: www.facebook.com
Address: 69.63.190.14

In the dst-address of the firewall rule.

Ok i will try this but NOTE am not using hotspot just only using bridge if this will make difference for the blocking ?
also i faced an issue that when i connect to mikrotik by wireless and measure my speed by app speedtest on iphone it give me only 5 MB and if i try it on the main modem it show 12 MB so i wounder is there an option that cut my speed and NOTE that if i connect by cable from mikrotik it will give me full speed 12 MB ??


SO did i miss something on the wireless options or the problem with the Mikrotik ??
