No problem hope you get help
Actually your client only need to allow echo requests and have file sharing service running.
Check, if echo is enabled in the firewall exceptions.
after the McAfee Agent is installed anything is done by the agent. There is no additional firewall configuration necessary for solidcore.
Check your EPO Server settings regarding the ports for the agent. This ports must be opend.
Afterwards EPO can connect to the client enabling a deployment task for solidcore.
Actually the McAfee software creates firewall exceptions during the installation.
On the Windows 2012 R2 Server:
All inbound TPC/UDP ports for C:\Program Files (x86)\McAfee\ePolicy Orchestrator\Server\bin\tomcat7.exe are allowed.
On the Windows 7 Client:
All inbound TPC/UDP ports for C:\Program Files\McAfee\Agent\macmnsvc.exe are allowed.
Make sure your network profile (Public, Private or Domain) are properly assigned to those firewall exceptions.
I will try these options and get back to you.
