The Configuration Options fields set up data replication between IPFEs, specify port ranges for TCP traffic, set application server monitoring parameters, and assign Target Set Addresses to IPFEs.
Internal IP addresses are used by the IPFEs to replicate association data. These addresses should reside on the IMI (Internal Management Interface) network.
A minimum port number and a maximum port number specify the range of ports for which the IPFE will accept traffic. If the port is outside of the specified range, the IPFE will ignore the packet and not forward it to the application servers.
Target Set Addresses (TSAs) are a list of public IP addresses to which clients will connect. These IP addresses must be accessible from the outside world. Through the TSA, incoming traffic will be distributed over a number of application servers that are configured as the Target Set IP List.
At least one TSA must be configured before adding any Diameter Local Nodes. Configuration of a TSA must be done after configuration of all networking interfaces.
