Greetings all, Being a previous tech for Sprint DSL I've got a little bit of general info for most DSL subscribers. Many DSL providers use PPPoE (Point to point protocol over Ethernet) to authenticate their subscribers. To ease up on customers having to use a connection box similar to dialup every time they want to get online, modems in the last 2 or so years have built in PPPoE that stores your username and password within the firmware. When you open any program that sends a request to the net, the modem throws the user/pass in front of that request. Depending on the company you have, your modem may stay automatically logged in anywhere from 5-30 or so minutes. Logging you off their network helps the ISP reuse IP addys along with lowering network usage in general. This though has been known to cause problems with older modems that want you to log in using a prompt on the PC as the computer doesn't always sent the user/pass after the first time. The modems used with Sprint are by a company called Zyxel. They use the 645 series modem currently, which are "routed modems" that also have bridge capability for use with a home router (linksys, Dlink, etc..) and even include a basic firewall. Most DSL modems that are in routed mode only hand out one IP address as the companies want you to pay for more addys each month. One nice way around this would be to use a home router, and bridge the modem. (Bridging the modem turns off ALL routing functions, NAT, and the firewall and pass everything, including the public routable IP addy directly to whatever computer/router you have connected to it. In Sprint's case when the modem is in it's typical routed mode (one computer connected direct to modem through a cross over cable) the modem has NAT, authentication, and the firewall turned on. This also makes the modem the "gateway" and a basic DNS and IP addy server for the computer to see. You can hard code the default IP address and DNS info that the modem gives out (get this info from your ISP) into the computer's NIC (Network card) if you don't trust that the modem will give it to the computer correctly on load. In my Sprint example the Zyxel modems (gateway) addy is 192.168.1.1 and the computer is given 192.168.1.2 along with DNS info that hardly ever changes. Now if you have a home router (wireless or wired) throw all that out the window. :) With many providers including Sprint, the routed modem they give you will butt heads with the router you buy and nothing happens. This can be due to double NAT (Network address translation) This is when the public IP address from the modem is changed to a 192.168 address (as an example) then it goes through your home router, it's changed again to either another 192.168 address or the same one again, then goes to the computer. This typically kills if not slows down your connection. To get around this, you can bridge your modem (Sprint has instructions at http://www.sprintdslhelp.com) and that will pass the public address from the phone line through the modem, so it gets to the home router. Your home router never sees the modem along the path. The only thing you then have to do would be to set the router for PPPoE (so it can send the username and password since the modem has been silenced) put in your user/pass (many times it's your email address and password, but can be a number of things, then test the connection. When hooking up windows or linux boxes, you may only then have to set your nic for the gateway (the router's address) IP address that the router wants to give out, and DNS. You can also use the router's built in DHCP server to set everything for your computer. Hopefully that is a little info for people new to PPPoE wanting to set up their box, or network for the first time.
