The communication between IIS and Tomcat uses the HTTP protocol. IIS uses port 9090 to talk to Tomcat, Tomcat uses port 80 to talk to IIS.
Client-Server Communication:
For IIS SEP uses HTTP or HTTPS between the clients or Enforcers and the server. For the client server communication it uses port 80 (or 8014) and 443 by default. In addition, the Enforcers use RADIUS to communicate in real-time with the manager console for clients authentication. This is done on UDP port 1812.

8443 is used by the remote console to communicate with SEPM and the Replication Partners to replicate data.

8014 is used by the web console to communicate with SEPM Reporting component.
Client-Enforcer Authentication:
The clients communicate with the Enforcer using a proprietary communication protocol. This communication uses a challenge-response to authenticate the clients. The default port for this is UDP 39,999.
