FWIW, rebooting is almost never the answer to problems like this. Unlike Windows, Linux is not generally subject to system bugs, so if you have a problem, it's most likely a configuration issue (which won't be fixed by rebooting).

Which distribution are you using?
Has this system been working all along (then suddenly changed), or is this a fresh installation?

I ask because Red Hat 7.1 is more secure than previous versions, including some basic firewalling. A "filtered" port generally indicates that a firewall is blocking access to the port in question.

So, what kind of firewalling is in place?
