short answer: it's easy, no problem at all, nothing fancy or weird. actually, verizon is the most difficult example, but only because it takes extra work to get the account initailly activated, once that's out of the way it's, long answer: I have a few customers with verizon dsl service, same as you describe, pppoe, dynamic ip, it's no problem. the key is, just get any one of several readily available "broadband gateway router", they are available at office-max, office depot, staples, etc, and of course comp usa. some names I've used with mixed success, linksys, d-link, netgear. they are only about $120 to $190 and usually incorporate a 4 or 8 port switch, and some even include a print server and some now include a wireless access point too. (with wireless you are getting into the $300 range. The way I do it, I pop the install CD in my laptop and go through the gyrations of getting the account registered as if my laptop were the only PC. This could be done on a PC in the office but I just find it easier to usemy own. the dsl install cd forces you to install a special version of netscape from the CD, which it uses to log in to a special account activation server via the dsl. there is no way around this. it also installs a pppoe driver called "winpoet" and a vpn virtual network adapter. this is all needed for the PC to use the dsl directly, but is all unwelcome junk once the account is activated and and the router is doing the pppoe. You never need the stuff again, power-cycling the router or the modem, even for long times like weeks doesn't make a difference. once the account is activated and working, I put the router in place of my laptop, and reconfig my laptop network settings to talk to the LAN side of the router. I give the laptop an ip like 192.168.1.2, then use it to configure the router by doing https://192.168.1.1/ (LAN ip of the router), in the router config, you just: * set "ip is provided by provider" and leave all ip and dns fields emty * enable pppoe * fill in the username and password, gleaned from the account activation process when you installed the verizon CD * enable "connect on demand" and set a long idle timeout so it mostly just stays connected. * in the case of a LAN that includes a unix server, either make the unix server the "DMZ" or, define some NAT rules to forward incoming traffic on specific tcp/udp ports in to the unix servers LAN ip (such as 21,22,23,25,80,110) "DMZ" is just a special NAT rule that means forward all (0-65535) tcp and udp ports in to one of the LAN ip's. if there is not a unix box, you would make the NT server, or just pick an "important" pc, and make that the dmz, and you will be able to install pcanywhere on that PC and then youcan pcanywhere from your office to theirs at dsl speeds. you will need to have them tell you their ip each time for this but, there are a couple things you can set up to make this quick and simple, and it's worth the bother even for short sessions. * You may want to change the routers IP to conform to the existing LAN, if it was already a proper non-routable network (10.x.x.x or 192.168.x.x) * You may want to do one or more of the following with the dhcp server built into the router (damn these little miracle boxes do a lot huh?) - turn it off, since it's usually enabled by default, serving about 50 or 100 addresses - redice the range of addresses in its pool so that most PC's on the lan have static IP's and there is also a few addresses set aside for dhcp so that you can also have people with laptops just walk in a plug them in and have them auto-configure. - leave it enabled, maybe increase it's range so it serves almost all 253 available addresses ( be sure to avoide the unix servers IP, which should remain static) and configure all the PC's for "detect IP automatically) this way from now on you never have to figure out what is an available IP to use when installing new pc's or reconfiguring dead/replaced ones. * since these things are configured via http or telnet or both, sometimes they include the option to enable or disable the ability to administer the router from outside the LAN. since the common http and telnet ports are probably going to be mapped with NAT to be passed off to the unix box, sometimes there is an option to have the built-in web server and telnetd listen on non-standard ports. if there is no option to move the built-in servers to other ports, then you won't be able to administer the router from your office except by telnetting in to the unix box, and from there telnetting to the LAN ip of the router, or if the connection is good, and you have access to a unix console, you can fire up X, open an xterm and set and export DISPLAY=your-ip:0, run "xhosts +", telnet to the remote unix, then run netscape on their box, netscape will then display on your screen, but it'll be running on their box, and you can then use it to http to the LAN side of their router. I use this sometimes to run "printtool" on remote linux boxes, and "netscape fast start internet configuration" on remote sco boxes. It's not too useful for administering the router though, because you need the router to be doing it's job in order to get to the unixbox, in order to get to the private side of the router. sometimes you can dial in to the unix box and run lynx to administer the router if the router is not working.
also change the default password since everyone knows the default passwords of all the mass-produced routers. also, don't wait for the call-backs, simply check the manufacturer web site and upgrade the router firmware. In this case, do not waste the time with the usually better practice of only upgrading something if it actually breaks in some way. When I say I've had mixed success, I mean, I've used mostly linksys, and within that group, in most cases the thing went in and started out working just fine, but turned out to lock up under a little load, or, perform terribly under a little load. of these, most were fixed by upgrading the firmware, but some just turned out to be "bad" and getting a warranty replacement one (even though it's the same model) from the store, (and upgrading that ones firmware too) fixed it. And even among "good" ones, usually they need to power-cycled once in a while, varying from once a week to once in a month or two. I have a d-link at home, a 8-port switch model, with only a dormant freebsd box, a mostly dormant win2k box, and once in a while my laptop, and it needs to be power-cycled every couple days. I had one recently that would lose it's configuration every day or so. (power-cycling is safe to do normally btw) If it loses it's config, such as by hitting the tiny reset button, it only takes a minute to just punch the stuff back in and You can sometimes even show a user how to do it, and leave them a cheat sheet with the list of numbers to fill in and check-boxes to hit. There is no more need for the install cd or the winpoet junk. I'm sure there are better boxes out there, but the point of the discussion was that there is no great difficulty using verizon's or anyone elses dsl with any unix. On possible exception would be those services where the modem uses only a usb cable and not ethernet, and/or those cable services where they install a cable-modem card in the PC, and the cable only downloads, and uploads (even the tiny upload that is the text of URL you typed in to the address bar to ask for a page) takes place over a regular telephone modem) that is for the verizon/bell-atlantic modems. many other services use a modem that actually is also a NAT-capable router and 4 or 8 port hub or switch itself, and sometimes they offer the option for a "un-managed" account, which means they let you have the password to the modem and you can configure the router/dhcp/nat features yourself, but usually you have to ask them to do it.in these cases you don't have to buy a router. there is nothing stopping you from just sticking you own router in there as described above even if the modem has a router, if it is difficult to get the provider to do what you want or you just don't want to have to call them every time you want to play with some new service or something. You *could* install 2 nic's in a pc, install the winpoet crap on the pc, install wingate, or use windows me/2000 built in connection-sharing driver instead of installing a router. I think this is an absolutely terrible way to go, though I have seen it working in a few places. (I didn't set it up. I have set up wingate once, could not figure out the windows built-in stuff) maybe these cases were installed before these routers were such a commodity item. -- Brian K.
