No.

Hi Chris, My IP addresses are private and I am connected to the internet
via an ADSL modem/router and, yes, I ran nmap from my local machine. The
firewall in the modem/router is set to disallow ALL requests from the
internet so I thought I was safe from hackers. I used the graphical tool
for setting up the machine's firewall using High security and only
allowing ssh acess, so I assumed that all ports except those necessary
for email and web browsing were closed. The ip address for my internet
connection is dynamically assigned by my ISP so changes each time I
power on the machine.

I ran the tests from the web site provided by Ted and my machine passed
the test OK. Some ports were in stealth mode and all the others were
closed. Nothing was set by my machine, so, hopefully, I'm safe.

Thanks to both you and Ted.
