[HTCondor-users] how to add a machine to a pool if it can't connect with the central manager machine?

[Guang.Wei <492096437@xxxxxx>]

We have a condor pool and want to add a new machine to the pool.

For example, the pool have 4 machines in different places: A,B,C,D. A is the central manager.

Now we want to add a machine E into the pool.

The problem is the network condition of E: A and B can't connect with E. E can connect with A and B. C, D and E can connect with each other. 

Do you have any solutions to this?

can I make another machine C as central manager and let E connect with C?  can a pool have 2 machine as central manager?
