IPTables is used on the MFEL/MFVP to protect the unit, however during setup it might be an idea to disable it (temporarily) if you are unable to see certain IP Streams.
IPTables is a massivly complex topic, and I don't know that much about it, but what I do know is how to stop and start it.
service iptables status
service iptables stop
service iptables start
