An example of a multiple route table can be found in Figure 54.

TCP/IP Port Restriction
TCP and UDP protocols use ports to identify a unique origin or destination of communication with an application. Each port is assigned a small integer. You can configure port information if you want to restrict the use of a TCP or UDP port to one or more user IDs.
The range of port numbers is from 1 to 65535. However, ports
Because this range of port numbers,
The iSeries Add TCP/IP Port Restriction (ADDTCPPORT) command allows you to restrict usage of a single port or a range of ports to a particular iSeries user profile.
Restricting ports is like allocating ports to a specific user profile. When a socket application issues the bind() system call, or when a TCP/UDP Pascal API application issues a call to the TcpOpen, TcpWaitOpen, or UdpOpen function, the job’s user profile is checked against the list of user profiles that are associated with
