Figure 56. Add TCP/IP Port Restriction Display

Let us assume we have an application that uses Port 1060 in the TCP layer and we want to restrict its use to user profile GERRY. Type the information as shown in Figure 56.

Figure 57 shows what the display looks like after you enter port information for both user profiles PAOLO and GERRY.

Changes to the port restrictions take effect immediately. However, applications that are already active are not affected until they are restarted.
