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.



For example:

1) Allow all IP addresses

 Allow *

2) Allow only IP address that starts with 192.168

 Allow 192.168.*

3) Allow only a specific IP address (e.g. 192.168.101.2)

 Allow 192.168.101.2

4) Deny only IP address that starts with 192.168

 Deny 192.168.*
 Allow *
