RE: [swinog] vtx ADSL /30 subnet practice

Dear Daniel, and all, Yes, I confirm if you order a /30, /29, /28, etc to VTX, the first IP of the subnet is assigned to the CPE with the right mask associated. > > This setup works on Cisco and Zyxel ADSL as the WAN interface is using > > the IP from the LAN side and the LNS sees both a /32 and a /30 > > route...not sure about other xDSL CPEs though (o; I confirm, this setup works on most of the CPE. For exemple with a /30 you have one IP for your LAN gateway and one usable. That's normal, it's a /30. :) Have a nice day, Jerome > -----Message d'origine----- > De : swinog-bounces(a)lists.swinog.ch > [mailto:swinog-bounces@lists.swinog.ch] De la part de Daniel > Roethlisberger > Envoyé : dimanche, 3. juin 2007 22:46 > À : swinog(a)swinog.ch > Objet : Re: [swinog] vtx ADSL /30 subnet practice > > richard(a)routerlab.org <richard(a)routerlab.org> 2007-06-03: > > This setup works on Cisco and Zyxel ADSL as the WAN > interface is using > > the IP from the LAN side and the LNS sees both a /32 and a /30 > > route...not sure about other xDSL CPEs though (o; > > In this setup, the PPP endpoint address of the CPE router is > the same as it's LAN address, and the customer still gets his > /30 network to use as expected, i.e. there's an address left > for, say, a server. > > In the vtx case (if correct), there is nothing of the /30 > left to the customer to use, except the WAN address assigned > via PPPoX.

vtx ADSL /30 subnet practice
by Daniel Roethlisberger 03 Jun '07

03 Jun '07

It seems that vtx has some very strange way of configuring the /30 subnet when customers order 4 fix IP addresses. Normally when someone orders a /30, the ADSL router's PPP interface would get an address from an unrelated address range. The 4 addresses from the customer's /30 subnet can be used by the custumer for the network and broadcast addresses (-2), the router's LAN interface (-1), leaving one address for a server or desktop machine. However, this seems not to be the case at vtx.ch. As two vtx engineers explained to a (tech-savvy dipl. Inform.) customer, they use the addresses from the /30 subnet for the PPP link between their last router and the customer's ADSL router. So in effect, this means ordering a /30 subnet (the 4 fix IP addresses option) from vtx gets you the same as ordering a single fix IP address -- you get a static address on your ADSL router's PPPoA/PPPoE interface, period. To actually use the static address on a server/desktop, you need to either configure destination NAT on your router or operate it in bridging mode and run PPPoE directly from the server/desktop. Can anybody confirm that this is current practice at vtx? Are other providers doing the same? -Dan -- Daniel Roethlisberger <daniel(a)roe.ch>
