We are upgrading to 14 from 12.1.6 and noticed that on our 32 bit Win 7 Pro systems the firewall in SEP was disabled so when we enabled it in 14 it blocks all traffic except DNS resolutions and anything that SEP does.
Pinging the router which the computer is directly connected to returns a "General Failure." It cannot reach any sites even though it resolves the IP from the DNS server. We can bring up the network monitor inside SEP and see that it is blocking traffic but it doesn't log anything. We tried this on multiple hardware platforms. Also with the firewall on the SECARS test fails from a browser, however with wireshark we could see that SEP could communicate to the manager and live update works.
So we tested on Windows 7 PRO x64 and Windows 7 Enterprise x86, got the same results.
With Windows 7 Enterprise x64 everything worked fine. I don't see any settings that pertain specifically to x86 versus x64 on the manager. We did notice that there is an extra tab in "Network and Host Exploit Mitigation Settings", on the Win7 Ent x64. The tab was called "Microsoft Windows Networking" , I am not sure if this has anything to do with it or not.
We have about 500 systems running Windows 7 Pro x86 so would like to get the SEP firewall to work with that version of windows.
