Your modem has a NAT firewall in it and probably need to be configured.
Verizon's Westell 2200 has basic firewall features that are user selectable. One of the first things I noticed with the Westell 2200 last year was that I no longer received Windows Messaging Services spam. This isn't instant messaging spam (also called spim), but a whole other category of nasty stuff that takes the form of gray pop-up windows. Verizon's network was inundated with this stuff under the old Westell modem, unless you installed a firewall or disabled Windows Messaging Services (a networking messaging functionality provided in Windows). The Westell provides NAT services. So right out of the box, with the firewall features turned off, the Westell 2200 gets full "stealthed" scores from PC Flank. You have as much protection as you get from a good broadband router. The 2200's configuration screens come with three built-in firewall settings, and you can also customize your own setting. There are both inbound and outbound protections available with this firmware-based firewall.

By the way I like you taste in music. I also am a Floyd fan.
