<html><P>In my humble opinion...</P>
<P>It is always best to have a firewall between you and the outside world. In some circumstances, two firewalls back to back is even better (make sure the two are from different manufacturers...)</P>
<P>The folks at <A href="http://www.metasploit.com/">http://www.metasploit.com/</A> work on tools which exploit open ports and even with so few ports available, your system could be used as a "zombie" tool by malicious people.</P>
<P>So, put a firewall in, or install some kind of syslog filter/analyser which will at least notify you of weird things going on...</P>
