Dropping client access sessions over VPN

380 pts.
Client Access
My CA sessions keep dropping. My VPN connection is solid. I am using standard VPN provided by Windows XP. If I start up a MochaSoft session first (do not even need to sign on to AS/00) All my CA sessions stay connected. How come I have to have MochaSoft up to keep CA sessions going.

Thanks. We'll let you know when a new response is added.


please try to check the following:

* On your vpn server, double check your configurations, some VPN servers has default time session for clients which is quite shorter than you expected, so your connection keeps on dropping.

* try to have a continuous ping from a remote place to your VPN server, maybe there are RTO’s that leads to connection failure.

* contact your ISP and verify if your connection has restrictions with regards to VPN connection. UDP port 500 on your ISP should be open.

Hope this works..

    It may be that Mocha sets a "keep alive" value and CA doesn't by default. You can change this by editing the .WS file. Try the following article:

    I got to the link. Had to clean it up a bit... I did as the link suggested. Added KeepAlive=Y right after the [Telnet5250] option in the xxx.ws file. It did not make a difference at all. My session died after about 10 minutes. I did not try the CWBCOPWR *CMD to change settings. Can that command show you what the setting are.? I prompted the command for its parms... shown below Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp. C:Documents and SettingsHP_Administrator>CWBCOPWR /?
