        We have two routers connected to the Internet configured 
        identically, as well as two hubs, two firewalls, and two 
        hubs on the other side.  Then we installed Black Box 
        power on/off switches (one on each router, and one on 
        each hub at the other end).  This way we can leave one 
        network up and the other powered off.  If any device in 
        the "primary" network fails, with a simple phone call 
        (our help desk can even do this), one network can be 
        powered off and the other powered up.  (this way all 
        equipment can actually have the same IP addresses too.)
        
        Hope this helps -
        
        Laura

My company wants to move toward Electronic Commerce on the Internet. 
 One of the requirements would be a highly available, secure 
connection.  One of the ideas I have considered is two firewalls going 
out over two routers to two wide area links to two ISPs.  This is a 
pretty brute force approach.
        
Does anyone have any ideas to share on how we might build an Internet 
connection that would approach 100 percent availability?
        
Thanks for all your help.
