we actually have the problem that some VPN clients disconnect when they are
inactive for a couple of minutes.
I found a posting from June the someone's got a modified ikeapp.exe (or
ikeapps.dll) to get the keep-alive signal sent every minute instead of 15 or
30. (or whatever Novell standard is)

Can someone help me where I can get this file?

Are there other smart solutions for that problem?

I appreciate your support.
