They actually don't even offer ADSL2+ in a lot places, including the exchange my home is connected to. Virgin Media, the largest Cable operator, offer FTTC (at least their advertisment sounds like that) but I don't want to use their service for a variety of reasons. You can get Ethernet To The Home but it is very expensive. British Telecom offer neither Fibre To The Cabinet nor Fibre To The Home.

I have heard rumors that in parts of Europe there are very cheap fiber and ethernet alternatives to dsl? I was under the impression that DSL was a lame USA functionality incorporated so they can save money and set back real connectivity. It's a shame you don't have the option of something to the sort. Chears, Noah Ah, I see. I have heard rumors that in parts of Europe there are very cheap fiber and ethernet alternatives to dsl?

The problems were:

  • MTU issues (MSS clamping required even for IPv6).
  • Lack of reliability of the A-DSL modem.
  • Two devices (with two power bricks) instead of one.

Back then it was also more tricky to find a small, silent and lower power hardware platform for NetBSD. Thanks to the Netbook boom there a lot of Nettop systems on the market these days which can do that job nicely.

My isp provides a 'modem' that I have in bridge mode so I don't have to NAT twice and loose a performance ratio. It just passes straight ethernet frames over, not limiting me to a low ram and cpu device. After that, BSD does everything. altq, firewalling, nat, etc. What problem do you see with this method?

But that would require ADSL2+ capabable hardware with NetBSD drivers. The best option is probably one of these cards: http://www.traverse.com.au/productview.php?product_id=3D115 But they are not exactly cheap and there is no NetBSD driver yet. Writting a driver would be possible but I lack time and a second ADSL link or equipment for testing. I would love to use a NetBSD router.

So I visited your website. My question is why you don't make your own router. Is it because it doesn't have as many networking options available as business grade proprietary, embedded networking systems? I hear from admins that they are jumping to juniper networks now in cases, claiming that it is far superior to cisco.
