I will install Cisco PI 2.0 behind a firewall for security reason. The WLC5508 is before a firewall. Can anybody let me know which TCP/UDP ports need to be open specifically between the Cisco PI and WLC? I don't see that from the below link.
Cisco Prime Infrastructure 2.0 Quick Start Guide
If the Controller is behind a firewall, make sure that the UDP ports 161 and 162, which are used for SNMP communication between PI and WLC, are opened.
PI cannot communicate with WLC if it is behind a NAT device. This is not a supported configuration. The PI server needs direct IP connectivity to the controller.

When a PI server and a PI user interface are on different sides of a firewall, they cannot communicate unless these ports on the firewall are open to two-way traffic:
80 (for initial http)
162 (trap port)
Open these ports in order to configure your firewall to allow communications between a PI server and a PI user interface.
