Block Services

Like the situation mentioned before, the option to block services only Enable (unlocked) or Disable (locked) the normal operation of MSN, ICQ and mIRC services, so LAN users can have or not Internet access to that services (Figure 4.2). For MSN Messenger it's possible to make exceptions for some specific IP's or subnets. In the example at Figure 4.3 the machine 192.168.1.150 and machines from 192.168.1.96 to 192.168.1.110 will have MSN access.
