Determine default port for Single Sign-On

You must also determine if the default port of 8043 on the CIC server (service provider) will not conflict with any other usage of that network port or within your network, such as firewall settings, Network Address Translation, Session Border Controllers, and so on.If you plan to use ICWS in your CIC environment, you must ensure that the default port of 8019 will not conflict with the same network entities.If you later decide to change the port number, you must create a new ACS URL address and supply it to the identity provider when you change the port number on the CIC or ICWS server and any involved network entities.
