Thanks for the input. My little session of craziness wore off because
things have been better around here, but I am interested in your
comment. The one thing that I know about the DSL in the area is
this....they have what they call "Sticky" IP Addresses and not
"Static" IP Addresses, thus the reason for the PPPoE. Sound
reasonable or are they leaving out some necessary information?
I almost mentioned that in the last post, then deleted it back out before
posting. The "Sticky IP" is another example of marketing inventing terms
needlessly for things that already exist by well known names because they think
it will help sell more products to people (home user market) who don't know any
better and think they are getting something new and different. Sorry, I guess I
have a very negative view of marketing :-),...it is the bain of the IT
industry,...at least for the people who care what words mean and how things
really work.
PPPoE is a form of "dialup" technology and the address is given out by just
"good old fashion" DHCP. It just dials an IP# instead of a phone number.
Similar to VPN but without the encapsulation and encrytion (the Tunneling
effect). It follows the exact same pattern of operation as the old Modem Dialup
methods.
The Stinky IP is just "techno-slang" that is nothing more than a Reservation in
DHCP. So it is still DHCP,...it is still Dynamically Assigned,...it is just
that you get dymanically assigned the same number every time. It probably will
not improve anything, although it is better than nothing.
The problem isn't the different -vs- same number every time that is the problem
(that isn't the PPPoE part of it). The PPPoE part of it is the "dialup" element
of it. It has a habit of timing out, "hanging up" the connection,...and then
not redialing and reconnecting on demand like it should.
The home user NAT Firewalls (Marketing incorrectly calls "routers") tend to
handle PPPoE fairly well since they were built with all the home user
technologies in mind and thier small firmware based OSs are just optimized for
this type of stuff. You could put one of those between the ISA and the DSL Line
if you don't mind the fact that you would have an additional subnet between the
LAN and the Internet,...actually this would create a Back-to-back DMZ.
These are of course my own views of this situation as my tagline says. No one
is obligated to listen to or to agree with me :-)
