Not yet but I'll look into it at some point in the future. What concerns me MORE is FTP and HTTP ports being open on my Netgear router. *Sigh*

Peace...

Take a look at my iptables thread posts in this forum - that should help a great deal - and read the comments from the Ubuntu forum on which the guide(s) are located.

Download the Netgear router documentation for your specific from the Netgear website if you don't already have it. There should be one there, like there is for the Linksys manuals in PDF. And also, make sure you have changed the default router admin password - a common vulnerability and easy to compromise for miscreants.

I changed the admin password when I first installed the router. I poked around the router's configuration interface and didn't seen anything related to FTP at all. We'll see if their doc mentions anything. My gut tells me it won't but I haven't actually looked.

Case solved: I used a different nmap scan and all open ports are bound to localhost and filtered.
