only ePo 4.0 was out back then, and yeah to WSUS. Below is what I have for my ports in ePo
|Agent-to-server communication port:||81|
|Agent wake-up communication port:||8181|
|Agent broadcast communication port:||8082|
|Event parser-to-application server communication port:||8445|
|Console-to-application server communication port:||8443|
|Sensor-to-server communication port:||8444|
Hope that helps you guys.
Is this configuration still working out for you? If so, can you tell me exactly how you configured ePO and WSUS so they could peacfully coexist on the same server? Any help here would be greatly appreciated as it may be that I will not have another machine on which to place WSUS.
