Hi,

Sorry for the response time, I've other project and thing to do before 
continue to configure the grid.

So, I will summarize and ask my question:

 My topology:
I ve two "sub-network" separate by a firewall/router
- first sub-net composed of master + submit/execute nodes
- second sub-net composed of submit/execute nodes

 My configuration:
I used a shared port : 9618 in all nodes
and a range port : 9600 to 12000
when I look netstat It's ok ports I configure are used.

 The objectif is to be able to use as minimum one submit machine on each 
sub-net and obviously every execute nodes

 My questions are:
My configuration is it correct to do that ?
And what ports I need to open ? in what way ?
(Is it possible to open one ore two ports for everything ?)


To finish:

You say:
>>If the large outbound port range is a problem, you can configure the 
>>execute nodes to use CCB

What is the CCB ? I never see anything about this in the HTCondor 
documentation for the time

Thank you for your time.
Have a nice day.
