I have also posted about this at the old forum: http://pub24.ezboard.com/fsecureyesecurityfrm3.showMessage?topicID=9.topic I am talking about this situation: 1. You have an (A)DSL modem where at the LAN side an USB cable comes out of it that you have to plug into your computer (usually there comes an Ethernet-cable out of the modem that you have to plug into your computer, but there are USB-ADSL modems like the Alcatel Speed Touch USB that does not have such an Ethernet cable connecting to your PC). 2. AND you want to use a router (hardware firewall). Then you have not much choices. The reason why there is a problem, is described here: http://www.practicallynetworked.com/networking/usb_modems.htm As far as I know there is at the moment only one router that you can use in this situation: Draytek Vigor 2200USB. More info about the Vigor 2200USB: http://www.seg.co.uk/draytek/products/vigor2200usb.html Tests of the Vigor 2200USB: http://www.practicallynetworked.com/review.asp?pid=427 http://www.adslguide.org.uk/hardware/reviews/2001/q4/draytek_vigor2200usb.asp http://www.homenethelp.com/web/review/draytek-vigor2200e.asp At the LAN side of the Vigor 2200USB comes an Ethernet cable. So to connect the Vigor 2200USB to your PC, you have to put an Ethernet-card into your PC. Or you could use an Ethernet-USB adaptor like the Linksys USB 100TX: http://www.linksys.com/Products/product.asp?grid=26&prid=126 Instead of using the Vigor 2200USB router you could build your own gateway machine using for example an old Pentium I machine, and install one of the Linux based firewalls on it. But that gateway machine has to have an USB connection to connect to your USB-ADSL modem, and you have to make sure that that Linux-OS can handle USB.
