Michael,

VCL always needs fixed DHCP on the private network.  For the public network, 
"static" means that once sshd is up on a node on the private interface, VCL 
will connect to the node across the private network and set the public IP on 
the public interface to what is in the database at computer.IPaddress (the 
public address) for that node.  It should not be setting the public address to 
what is in the database at computer.privateIPaddress.

Prior to 2.3 (unreleased), you can only set the private address of a node when 
you initially add it, and only using the "add multiple computers" part of the 
site (hint: you can actually add a single computer using the "add multiple" 
pages). For any nodes you already have in the database, you will need to 
change the private IP address directly in the database if so desired.

So, you should be able to obtain your goal using the "static" setting.
