 Date:  Tue, 14 Jun 2005 12:31:24 -0500

I have about 6 IPsec tunnels up 24x7 and have very few problems.  However, 
I'm not using any Mobile Clients.  Also, for this to work you need static 
addresses on both ends or at least addresses the stay the same for months at 
a time. An example of one of my tunnels follows:

LAN Subnet
remote gateway's IP
Description of tunnel
Domain name xyz.com
Pre-Shared Key goes here

Hope that helps.
