I have a Ubuntu server running apache2 with 5 virtual ip addresses. The
server is connected to a 2Wire 1701HG router/dsl modem. The problem is
that there doesn't seem to be a way to get the 2Wire router to bridge
the virtual ips --- only the primary ip gets passed thru the router. The
at&t tech is saying that the problem is that the virtual ips have the
same MAC address and the primary ip address on the server and are
therefore being ignored. He's saying that I need to use DHCP and set up
multiple machines to eliminate the virtual ips. WTF? There must be a way
to get the 2wire to bridge a block of ip addresses without having to use
DHCP and/or multiple nic cards. Has anyone figured out how to do this?

FYI: as an added complication, I don't want to mess up the other
machines on my network which do require that DHCP be active for some
machines.

Good luck with that 2Wire DSL modem/router. Have you tried cross-posting to
alt.att ? If it is an older unit maybe they would be willing to trade it in
for a newer model.

I think it's the only one available from AT&T. The 2Wire unit does seems
to be a one-trick pony. The static ip support is rather poor.

I was looking into getting a LinkSys dsl/router (Linksys EtherFast
Cable/DSL Router BEFSR41, for example). It looks more capable. Has
anyone used a third party dsl modem/router with AT&T's dsl service? Is
the LinkSys going to solve my problem or am I going to need to set up
the Ubuntu system with a second network card and use it as the DHCP
server for my private net?

The software in DSL modems is crap. Put it in bridge mode and put a router
behind it to handle PPPoE, routing, and firewalling.

Fair enough. What would be a good choice for router that would handle a
mix of static ips and provide DHCP services for the windoze boxes
browsing the web? We only have about 6 machines that need to be
serviced, so a small router will do.

I use an old Aptiva running Debian, but just about any hardware running a
basic (not full) install of just about any distribution of Linux or BSD
will do.

So let me see if I understand this: All I need to do is to set the 2Wire
dsl modem to bridge mode, plug it into the Linux LAMP server and set up
the PPPoE net interface. Then use the second ethernet NIC for my DHCP
server with masquerading NAT rules set in ipchains. Sound reasonable?

btw: What's a good PPPoE package to use? I'm on Ubuntu Fiesty Fawn.

Seems likely, though I'd use seperate hardware for the router. Anything
you can install Linux on will work. What model modem do you have?

Pretty much every distribution includes a PPPoE package in the base
install. In Debian the name of the package is just 'pppoe' (source
rp-pppoe). It is configured with pppoeconf.

The modem is a 2Wire model 1701HG.

I have FiestyFawn installed right now on my LAMP server, but I don't
have the pppoe installed yet. I'll install it and give it a test drive
in the next day or two. The machine is on the other side of town.
