I am not sure I fully understand the issue, but you might try a configuration marco which adds condor as an exception to the firewall:
ADD_WINDOWS_FIREWALL_EXCEPTION
When set to False, the
condor_master will not automatically add HTCondor to the Windows
Firewall list of trusted applications. Such trusted applications can
accept incoming connections without interference from the firewall. This
only affects machines running Windows XP SP2 or higher. The default
is True.
