[OMPI users] Help: Firewall problems

Hi, I remembered MPI does not count on TCP/IP but why default iptables will prevent the MPI programs from running? After I stop iptables then programs run well. I use Ethernet as connection. Could anyone tell me tips about fix this problem? Thank you very much. Amy
