I'm using Netgear Prosafe Pro VPN client software.
Everything seems to work OK except:
When the Windows firewall is turned on for either Public or Private networks, the ipsec VPN tunnel won't open up.
I'm not aware of any firewall settings that need to be addressed to make it work.
Can someone point me in the right direction with a URL or .... ?

Well, it's already working on other clients.  It's just this one Windows 8.1 client that I'm trying to get to work WITH the Windows firewall turned on.  Or maybe this is a problem on all Windows 8.1 (only) clients.  

The site terminating device is a Netgear Prosafe router VPN implementation and it's working fine.

Well, I presume you don't mean the Windows firewall ports, eh?  The link talks about router ports and those aren't being an issue.

I found this and fixed it:
Ports 500 and 4500 for both TCP and UDP have to be open in the Windows firewall on the client.

While that may not be too surprising, it appears that the Netgear install went part of the way there .. and maybe, erroneously, all the way there .. sorta.

There were TWO UPD ports 500 and TWO UDP ports 4500 opened and NO TCP ports 500 nor 4500 opened.   Whether this came as a result of the client program install or as a result of human error isn't known.  

Anyway, it was fixed by opening ports 500 and 4500 for TCP.  The necessary information was clearly stated on page *133* of the VPN Client User Manual.
