If you have a router, then the ADSL connection you have is handled by
the router, and is invisible to you, on the LAN side of the router. The
router could be connecting to the WAN via a piece of wet string, as far
as you care. So you should just have eth0 do DHCP and leave it connected
to the router. You'll get an address like 192.168.1.2 from the router.
You don't need ppp0 at all; to Centos the router appears like a LAN that
routes to the Internet.

In Windows, do "ipconfig" in a Command window, and you'll see what
I
mean. You should see something similar with ifconfig in Centos.

Dan: Thank you for replying! I will try what you suggested, ASAP. Yesterday
was Friday the 13th.... I need to get this working, before I try to get my
Firewall/Router working!  Lanny

Some pain-in-the-ass ISP's force you to do PPPoE instead of DHCP. Some
give you a DSL modem that does NAT and the PPPoE stuff for you, some
don't. If you have one that doesn't, a cheap Linksys "router"
can do the
NAT and PPPoE for you if you don't fee comfortable doing it in Linux.

I prefer to to use a Sangoma S518 ADSL PCI card for $120US and do
everything on the Linux side. Fortunately, I have a static and not
dynamic address, but the majority is the same. The big advantage is that
I can do traffic shaping / QoS without dealing with massive modem
buffers which can totally screw that up. It's good enough that I can run
torrents, interactive ssh sessions, and VoIP calls all at the same time
on a 1.5/384 DSL connection.

While this doesn't fix your problem, it's food for thought.

Walt in our former home, we had Cable Modem access for 3+ years and I
used a Linksys Router/Switch there. We live in South America, so I'd
need to have one shipped from the states. I think I can get it going,
with IPCop or Devil-Linux.

Our new connection is 256. After using dial up for 3 1/4 years, that's
fast.  :-) It's a lot slower than when we had Cable Modem service, but a
huge improvement!  I wanted WiMAX access, which is available in the city
of Cali, but it's not available in our town and who knows when if ever
it will be available.

I downloaded the latest versions of Devil-Linux and IPCop this morning.
They both have things I like. Devil-Linux does not require a hard drive
and runs off a CD-ROM and a write protected floppy, which for security,
I think is better. IPCop has much more documentation, can run headless
and has some other things I like. I think I will try IPCop first.

Thanks much for your input! Lanny

William: I came in here about 430 this morning and I
installed/configured IPCop 1.4.15 on a P3 500 MHz with 384 RAM. I'm
online with the box running headless (I disconnected the monitor,
keyboard and mouse). I was able to get to it via the web interface and
did a backup to floppy disks. When I have time, I will explore the
administration manual more and the web interface. IPCop has excellent
documentation! Lanny
