Chapter 10. TN3270 Client Configuration
10-10 707158-003
An example of the Manage TN3270 Client Access panel is displayed below.
Field Definitions:
TN3270 Client Access Entries: This is a list of Client Access entries that have already
been defined (the above panel shows a single entry). Entries can be added by selecting
the appropriate information and pressing the [Add/Modify] button.
Note that you will still need to press the [Update] button prior to leaving the panel to
make the changes take effect.
Local IP Address: This field allows you to define whether you want to specify a
specific local IP address to be associated with the port number, or allow the port number
to be used by all local addresses, for the entry you are defining. If you use the default
value ‘*.*.*.*’ then the entry you create will apply to all network adapters used for client
access. You can also select one of the local IP interfaces from the dropdown control to
specify that this entry applies to only that interface.
Port: This dropdown control lists all of the TCP listen ports that have been defined for
TN3270 clients. Remember that how the port was defined determines whether the clients
need to use encryption or not.
Client IP Address: An IP address can be specified allowing you to pin a particular
client’s access to their IP address. You can also use wild cards (asterisk) to define subnets
or groups of clients. By using the value of ‘*.*.*.*’ all users connecting to the specified
port will make use of the resource(s) specified. Similarly you could limit access to a class
C subnet by using an entry similar to ‘195.17.34.*’. Anyone on that subnet could gain
access by meeting the port/local address requirement. Subnet access is usually associated
with access to a pool.
