this is the key problem.

you need to tell condor which IP addresses are allowed to do certain
operations.  look in the condor_config file for the string "HOSTALLOW"
and set them to something like this:

HOSTALLOW_READ = 10.1.*
HOSTALLOW_WRITE = 10.1.*
HOSTALLOW_ADMINISTRATOR = $(CONDOR_HOST)

this will allow machines in those networks to join your pool, run and/or submit
jobs depending on which daemons they are running.

it also makes it so only the central manager can issue administrative commands.
you may wish to make the central manager a different machine from your main
submit point if you do not trust users on the submit machine not to say, turn
off condor.

i hope that helps!
