RE: [NF] What are people doing with cable interfaces?
If you look around the 10/100 NICs can be had for about $10.00 each, the 100/1000 for about $50.00, an old Pentium(anything w 32mb ram) $50.oo bucks, the time it takes to make it work PRICELESS. It's just an option, if you don't like don't use it.

And I didn't say I wasn't going to to tell you why, just not NOW. Stop putting words in my mouth. I already have a wife. or what you plan to use it for, but now you want us to explain to > you how to set it up? As Ethan Hunt says in MI, "It's much worse than that." Actually, there are two reasons... First, remember the scene in Cheers where Sam is making mistakes ordering things, and one day, a delivery guy drops off a stack of 2x4s, a dozen bags of concrete, and a wheelbarrow? Woody bids the guy goodbye after the requisite spirited exchange, then closes the door, looks at all this stuff in the middle of the bar floor, and says, "Well, now the only question left is... what am I going to build?" Same thing here - I have a line. What might I do with it? Second, I didn't want to predispose the answers. It's a long held truth that in survey taking, you first ask, "Tell us everything you liked about X." followed by "Tell us everything you disliked about X." Instead of "Please rate the following nine items on a scale of 1 to 5." If you provide stock answers, you automatically narrow down the answers you're going to get, without necessarily meaning to. So instead of leading people to the answers I wanted them to provide, I wanted a wide open field. Third, I do not know. I might use this as a spare access line in the event that the T1 goes down. I might use it as my main access line, ridding the T1 when contract time comes up. I might use it as a test line. I might move my T1 hosting to this line. I might decide it's a piece o' crap and get rid of it. I do not know. I was looking for a variety of possibilities. :) So there are my two reasons. >> At the end of the line coming in from out-of-doors, there's a box the >> size of maybe six decks of playing cards.

Well, actually, it's a dark grey. Almost a dull black. Shiny on the front, too. Seriously, the box has NO markings, numbers, any ID whatsoever on it. It's small, grey, has six holes on the back (power, 4xEth, USB). Four stickers on the bottom that say "Cable RF Mac Add 20957297348" and a fifth that says that Time Warner will throw me in jail and pull out my fingernails if I even think about screwing with the box. Hence my confusion. And I like my fingernails. >> Tech support says that only one >> is active, but I don't quite believe him, as I can plug a box into any >> of them and get out. > > Tech support may not know what you were provisioned. Then they're not actually 'tech support', right? I did have to give them my account number, and they were able to tell me what my reverse DNS was. I'm expecting that they should know what they delivered to me, else what support are they going to be able to provide. Refer to previous email re MSFT vs Leafe tech support. >> I've got four static IP addresses. > > Is that what you ordered, or have you confirmed that's what you have? > How did you determine that? Well, cuz that's what I ordered, and I done went ahead and believed them. The bastards! Oh, I feel like such a foole! Oh, I also plugged a machine in, popped in my static IPs (below), and verified that all four do get out to the Web, and report back via www.myipaddress.com. I have a Web server on one of the IPs, and can http:/1.2.3.4 to the server from 1.2.3.5 successfully. > Since you can plug a box in and get to the internet, what IP address > do you get?

I lack the self-confidence that many of you have in trusting your HCPs to Mr. Dynamic, and so always statically assign IPs to boxen. So I entered 1.2.3.4 into my static IP for a test box. www.myipaddress.com says I'm on 1.2.3.4. If I do that for 1.2.3.7, I get a similar, warm and fuzzy response.

Yep, I figured if you had time enough to mess around with trying new things out you may as well have something to idle time away when you start to bang your head against the wall. As an aside, I use a SonicWall Pro 200, and most of my clients use SonicWall for their firewall/VPN solution (largely at my recommendation). I like SonicWalls for lots of reasons, mainly because they offer so much bang for less bucks than Cisco. If you have 2 SonicWall units (if I read your eMail correctly re: one behind each T1), with a single WAN port you can use one as a failover for the other. I have that set up at one client location, and it works real slick. It was a little tricky to set up, until I read the F'ing manual . But once set it works like a charm. Ciao!

The router side of the box routes the Ethernet from the modem to each of the four ports. Depending on the smarts of the device, it may be able to allocate one IP address to each port or do even fancier stuff. It may also include a firewall, NAT, DHCP, DNS, logging, content blocking, VPN support and lots of other stuff. > So what do I do now? What is it you want to do?

If the four IP addresses are to go to different devices, they need to be routed, either using the firmware in the device you have (the router) or by adding another device inline.

RE: [NF] What are people doing with cable interfaces?
I use a simple router (i.e. LinkSys; D-Link) I find it does not properly handle DNS and was constantly getting timeouts. Having just 2 boxes it was easily configured manually. Were I to have more boxes, I would use a dedicated firewall/dhcp Linux distro I could configure as needed. Running a business I would investigate a larger dedicated system (i.e. Sonic Wall; Panda GateDefender) Some of these products allow for fallback connections to the internet. http://www.sonicwall.com/ http://www.pandasoftware.com/products/Gatedefender_Integra.htm Tracy > -Original Message- > From: Whil Hentzen (Pro*) > > So what are y'all doing with a setup like this? > > Whil ___ Post Messages to: ProFox@leafe.com Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.

RE: [NF] What are people doing with cable interfaces?
Good Day, Whil! Out here in the Upstate NY/Rochester/Geneva area I have seen Time Warner/RoadRunner move to a combo Cable Modem/Router (often with WiFi) unit for both business class and residential use. These units can be configured as "Pass Through" devices where you end up with a WAN IP popping out of the LAN side, which requires you to use your own firewall, or as a Router where the LAN side pops out with a 192.168.1.nnn IP at all the LAN ports (and WiFi if that is turned on). For my clients I have always opted for the Pass Through configuration as their SonicWall firewalls are set up for incoming VPN use. For home users that are friends I have no problem with them using the Router configuration and saving a few bucks by not having to go out and buy a separate Router of their own. If the home users need a VPN to match a remote location I will go with Pass Through, then place a firewall with VPN behind the RR unit. So, how do you tell if you have the Pass Through (sometimes called "transparent mode") or Router configuration? From what I have seen the Router config is the default setup. One has to request the Pass Through configuration, then hope the RR folks know what the hell is meant by that. If the IP coming out the LAN ports (4 ports you mentioned coming out of the 6 playing card deck size box) are 192.168.1.nnn, then you have the Router setup, which is okay unless you need an incoming VPN based on your own firewall settings. In the case where you have the Router config the RR Tech Rep was somewhat correct in saying you only have one active IP, as he likely means (whether he knows it or not) you have only one WAN/Public IP. If you paid more for a static IP, than that is the static IP assigned to your unit on the WAN/Public side of the box. You can get multiple WAN IPs, static or dynamic, for real reasonable (no longer $50 each, now down to $10 each, per month of course). If the 4 ports are popping out something other than 192.168.nnn.nnn, then your unit is set up as Pass Through. If indeed you have 4 separate IPs in the non-192.168.nnn.nnn range then you have 4 WAN/Public IPs, whether static or not. If you did not request multiple WAN IPs this is an unlikely scenario. Now, for the $1,000 question... If you connect to one of the 4 ports with a PC, is it auto-assigning (DHCP) an IP to your PCs? Or do you have to set up each PC with a static IP (which you can do with a DHCP system anyway)? This is more a question out of curiosity than anything else. I have only seen DHCP configurations on the LAN ports with the new RR Cable Modem/Router units. You can still use static LAN IPs for your PCs with a DHCP unit. The advantage I see with DHCP is if the DNS Server IPs ever change, the PCs' DNS address is updated upon IP resetting/rebooting. But wait, there is more! If you are hosting web/eMail/ftp,etc. Servers, and have been using your own firewalls to manage all that, then you need to have the RR unit set up as a Pass Through configuration. That way your firewall(s) manage which ports are allowing Port Forwarding or DMZ management with your Servers. If you try to do that behind the RR unit in Router configuration you will have a real good time trying to get it configured properly. For me, I prefer the Pass Through config, then use my own equipment to manage the signal processing. I hope that helps ...

RE: [NF] What are people doing with cable interfaces?
I'm wonder how you are dealing with the two T1 lines and how many IPs you had. If you had 4 IPs why not do the same thing you are now? A possible solution would be to put 5 NICs in PC, Use 4 (100Mb) to attach to the RR and the 5th (Gigabyte card) to attach to your Switch on your Intranet. You can run the firewall, active virus, ... on the PC and forward the unique IPs to the system you want on you net. This is basically a cheap multi port router with all the options you want to load. There are many free Linux router packages out there that can even run from a floppy.

I've just acquired a line with Time-Warner BizClass. The rationale behind it, let's leave that for another time. So now I've got some pretty basic questions I've been spoiled for so long, with a pair of T1s coming into the house right next to this TW line... Kind of like the frustration at having to deal with a dial-up. Anyways, the fellow who installed it wasn't terribly helpful (BIG SURPRISE), nor were the folks on the other end of tech support. But that's OK, I can experiment. At the end of the line coming in from out-of-doors, there's a box the size of maybe six decks of playing cards. The line goes into it, and there are four Ethernet ports available. Tech support says that only one is active, but I don't quite believe him, as I can plug a box into any of them and get out. I've got four static IP addresses. I'm guessing this box-like thingee is a 'cable modem'. All it provides is access outside. No firewall, no nothing, right? So what do I do now? I could hook up a single box that's running a firewall as well. Block everything but 80, for example. I could hook up four boxes, too. But I'm not sure I'm comfortable having to mess with four firewalls on four boxes; that begins to become a lot of admin that I should be able to handle in a central point. So I could also plug a firewall into one of the cable modem ports, then a hub into the other side of the firewall, and plug boxen into the hub. JUST CAN'T DECIDE!! So what are y'all doing with a setup like this?
