The DSL and the WANs don't have anything to do with anything.
If all the LANs are in the same building you connect them with normal
ethernet with a LAN Router in between (I mean a "real" router, not a
home-user NAT-box).
You could use a Layer3 Switch which is a LAN Router and a network Switch
built into the same piece of hardware.
*One* nic per machine. Get rid of the 6 nics in the Server.
Networks are separate from computers. Computers live on the network just
like houses live on the streets. But the computers do not become the
network just like houses do not become the streets. A network should
function even if there is not one single computer on it. If you design a
network with that in mind you will be miles ahead.

Hi,
I can connect one network consisting of a switch & ADSL modem to the
internet (twice) and then join both of these networks together via the
internet. What I want to do is join the networks together before they hit
the
internet (physically located in the same building) - because it's a lot
quicker for me to access the other computers via 100Mbit switch then it
via
ADSL. I have two switches & two ADSL modems that sit on top of each other.
I
need to join these together.
I have a Windows 2008 Std Server with 6 NICs. This is what I want the end
result to be.
LAN
---------
192.168.10.0/24 - CompanyA
192.168.11.0/24 - CompanyB
192.168.12.0/24 - CompanyC
WAN
---------
192.168.0.1 - ADSL Modem 1
192.168.1.1 - ADSL Modem 2
These modems can run in bridge mode if that's a better way to go... They
are
just running in PPPoE at the moment.
What I'd really like to do is have all the modems plugged into a switch
and
then only using one interface on the server as that will allow me to have
5
network segments. As it stands we have 3 right now, and will have 5 in
about
a month with 5 ADSL modems. As mentioned above I can keep them all
separate
and link them via the internet but that is WAY slower then if they were
all
joined together before they hit the internet. These are 5 companies in the
same building using each others services, which they coud do via the
internet, but again that is slower then connecting directly via a LAN. I'm
effectively the 5th company as I support the other 4.
So I need to have all the nework segments talking to each other - which
I've
managed to setup. I then need to be able to specify which network segment
uses which ADSL modem - this is the part I haven't been able to setup yet.
The idea here is that, if one provider goes down I can just switch the
network segments over to the ADSL modems that working and everything keeps
working.
Thanks for your pointers,
ZaneB
