How block IP address:

PFsense is a free BSD and Firewall router .Through this firewall router we block IP addresses that listed in dhcp list or network list.

There are two methods in which we restrict the internet access of clients or users.

First Method:

Go to Firewall tab and select Rule option. Add rule on lan interface .Select action as a “Block” Condition On interface Select “LAN” and then on protocol portion add “any” or “TCP/UDP” then go to Source section and select type as “Single host or Alias” and type on down line that IP address on which you want to block internet access .print screen given below.

Note*** First mach role will work so when we need to block any user we need to put rule at the top of the default rule in firewall section.
 

Action:                            Block

Interface:                       LAN

Protocol:                        Any

Type:                              ingle host or Alias

In second method it is important that proxy server already installed. Like Squid and squid guard.

Go to the services tab and point out to the Proxy server. In a proxy server we use Access control tab. In access tab we have an option with the name of “Band Host addresses” where we add that IP addresses we need to restrict internet access and then save.
