A new security feature is added to 4D 2004 to restrict and reinforce allow/deny access to 4D Server. This feature can be found under database Client-Server theme of the Database Preferences. The feature allows you to set access control rules for the database depending on 4D Client machine IP address.
1) Allow all IP addresses
2) Allow only IP address that starts with 192.168
3) Allow only a specific IP address (e.g. 192.168.101.2)
4) Deny only IP address that starts with 192.168
