Simply edit /etc/hosts and add line 127.0.0.1 facebook.com www.facebook.com and others what should be disabled. FB works on DNS, and this modification redirects all trafic to internal ip 127.0.0.1 .

This is a nice article for iptables. I’m using it to block access from countries that we do not do business. Your readers could download the free list from ip2location.com/free/visitor-blocker and it is working fine using iptables.

But before allowing them we have to block the FTP at all and then I’ll keep adding IDs which I want to be allowed.
So What will be the first step?

@Ravinder,

You can block facebook.com for particular network IP address and rest allowed using iptables as shown.

# iptables -I FORWARD ! -s 192.168.10.16 -m string --algo bm --string "facebook.com" -j DROP
