It does take multiple things to get it to work reliably on Windows Vista and
Windows 7: Windows registry settings, .ws file settings, and other System i
Access settings. We have about 40 people who access our systems via VPN
either full-time (telecommuters) or occasionally (on-call). After doing all
of the following, no one has timeout problems anymore. We are using a
Fortigate Firewall for our VPN connections and have turned off idle timeout
in the Fortigate for the VPN connections. Each PC uses a FortiGuard SSL VPN
client where keep-alive is turned on. We still needed the following things
for it to work properly.
Windows Registry Settings
Sets the interval to 5 seconds and the time to 10 seconds.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters]
"KeepAliveTime"=dword:00002710
"KeepAliveInterval"=dword:00001388
System i Access Workstation (.ws) Files
Both sections are needed.
[Communication]
KeepAlive=Y
[Telnet5250]
KeepAlive=Y
System i Access KeepAlive Settings
The first command turns on keep-alive for everything except telnet (which
uses the registry settings above). The second command sets the interval to
5 seconds and the time to 10 seconds.
From a command prompt type:
cwbcopwr /svc:all /ka:1
cwbcopwr /mka:5,10
You can experiment with different settings for the interval and time both in
the Windows registry settings and the second command for the System i Access
settings. Lower settings didn't work well for us.
Reboot the PC after configuring everything.

I sort had a feeling that might be the answer but I can't find it either.

I have found the more reliable way to fix this issue is a Windows OS
Change.. The change sets the Keepalive or similar parm a value like
2 minutes. Wish I could find that MS KB article. I remember the
registry
hack
or what ever was a little different per Windows OS level.
I will see if I can find the KB
