CCB should not be required in your situation if you can open a 
sufficiently large outbound port range on the submit machines. That's 
the simplest thing to do.  I suggested using CCB only if you need to 
reduce the number of outbound ports that must be opened from the submit 
machines.  By configuring the execute nodes to use CCB, you cause 
connections between the submit and execute machines to be incoming 
connections on the submit machine.  Since incoming connections use the 
shared port, this configuration requires a much smaller number of ports 
on the submit machine.
