Hi folks,

Is it possible to connect a front end running on my OS X laptop to a  
remote kernel on a Unix host in a case where the laptop is at home,  
where my network connection does not provide me with a static IP  
address?  A diagnostic web site at my home institution reports that  
my home computer's address is something like this:  But it's not always the same.

I am able to connect when I bring my laptop to work and put it on a  
static IP.  I accepted all the defaults in "Kernel Configuration"  
except that I selected "Remote Machine" and specified the correct  
hostname.  That means that "Arguments to MLOpen" is

   -LinkMode Listen -LinkProtocol TCPIP -LinkOptions MLDontInteract

and "Lauch Command" is

   `java` -jar "`mathssh`" ssgubser at math - 
mathlink -LinkMode Connect -LinkProtocol TCPIP -LinkName "`linkname`"  
-LinkHost `ipaddress`

I have the impression that VPN may solve my problem.  Has anyone  
successfully done what I'm trying to do through VPN?

I also have the impression that setting up an ssh tunnel might work.   
I have an appropriate gateway computer...  Has anyone made this kind  
of setup work?
