If your central manager [collector] and submit machines [schedd] are on 
the public network aka these machines are not on a NAT, it should be 
trivially easy to support compute nodes that are sitting on a NAT or 
behind a firewall.  The trick is to turn on CCB (Condor Connection 
Broker) support in your config file, which typically means just adding 
two lines into condor_config.  See

http://research.cs.wisc.edu/condor/manual/v7.6/3_7Networking_includes.html#SECTION00474000000000000000


Unfortunately, CCB does not support standard universe jobs, but 
vanilla/parallel etc is all good.
