VDSL2 Modem and Untangle

post #1 of 9
Thread Starter 
I use Qwest for my ISP mainly because they allow home web site hosting.Qwest recently went to VDSL2 technology. I also run an Untangle box. What I had to do was buy a 130.00 VDSL2 modem, put it in bridge mode,then connect it to my Untangle via the RJ-45 Ethernet cable connection. Everything works perfect except I am wondering how to avoid buying these modems,simply to put them in bridge mode. It is like I am buying a very expensive interface changer. I find plenty of "build your own router" tutorials on the net (but using Ethernet technology for your connection to the web). As you know VDSL2 uses the RJ-11 connector (it is a telephone connection). When are we who use VDSL2 technology going to be presented with the "build it yourself" option. Perhaps there is a inexpensive device that I can use besides a full on modem that I waste by putting it in bridge mode.

At least you don't have to buy one of these:

You could get a modem card, but I have never seen one cheaper than $300

I was wondering if since I bridge the modem does this relieve me of the need for a VDSL2 product. What I mean is, would a bridged adsl product work just as well since I put the device in bridge mode? I have an Actiontech adsl modem that is out of spec for VDSL2 usage perhaps when bridged and connected to my Untangle (or comparable device) it will work.Qwest said "NO", even if the modem will be bridged it still needs to be a VDSL2 product.I did not get the feeling the person I was talking to knew much about performance in bridge mode.I simply could try it,nothing to loose there.Those microATX atom cpu based routers that you build yourself and load up with open source apps are very interesting.My whole deal is trying to get away from paying 50.00 per month for Untangle.I do not need the support (it was a great Natting and routing learning tool) but I do not neede help in this area anymore.I do like getting all the apps that come with the 50.00 per month price, just not the price. I checked and if I went to PFsense it is another 100.00 per year for roughly the same service.

You still need a VDSL2 product to utilize VDSL2 features.

What you are outlining would be similar to trying to connect to an 802.11N access point using only a B compatible adapter, and then wondering why you only achieve 11 mbps.

Can you briefly outline what is still going on inside a bridged modem? No routing or PPPoe or NAT functions are operational (that is happening in the Untangle). I conclude more than just a path is being provided but how much more? To bridge my modem I simply check one box that says something along the lines of "allow 1354 (I do not know if these numbers are correct) transparent bridge mode" and that is all I do with the modem.

Think layer 1. You still require the protocols for negotiation and maintenance for the physical link itself, however in bridge mode your Untangle setup would handle authentication and implementation of all other protocols up the OSI chain(PPPoE, acquiring IP, performing PAT, etc).

I conclude the bridged adsl modem could not negotiate the layer 1 requirements due to not having the different level of componets required for the faster VDSL2 connection,sound OK or not?

EDIT: since I have the itch and the parts I will buil an Atom based miniATX router with the Linux router app and all the open source apps you would want in a firewall.

This is the "base" for my homebuilt router. The dual NIC's is what sold me. I have found so much information and links to open source apps that I think this job is going to be a lot of fun. Will it end up cheaper than a store bought router, not by a long shot, but it sure will be a lot of fun,besides I needed a project with a heavy dose of Linux in it.
