Trying to Block few sites

Hi Guys One of our client that is small company due to BW limitation requires we block all social media sites. so my fast strategy was Class Map but I had no lack, below is the class mp class-map match-any url-block-class match protocol http url "youtube" match protocol http url "facebook" ! ! policy-map url-block-policy class url-block-class drop When I applied to the WAN interface it had no effect what so ever, I applied on the out direction

Attempt Number 2,I tried ACL as below

access-list 101 deny tcp any host 157.240.1.35 eq www access-list 101 permit tcp any any eq www with the ACL when I applied to the WAN interface I loose all internet connections even though I have the permit any any, I am not sure what I missing here but this seems to be my best solution.

WAN Interface Config as below interface FastEthernet0/1 description WAN ip address 192.168.1.254 255.255.255.0 ip nbar protocol-discovery ip nat outside ip virtual-reassembly duplex auto speed auto end
