Great to hear that it is working for you. I should leave this to Luke and others with more experience to answer, but a cheap and easy solution if the machines are physically close to each other might be to put all your machines behind a hardware firewall (router). Then you can be somewhat more comfortable about turning off the actual machine firewalls. I don't have any other suggestions. You might also want to check on the MPICH or lam-mpi sites and email lists (even if you aren't using those softwares, as I think they have the same issues to deal with as far as firewalls).
