Using 2 different ip configurations on one pc

[Roger Rogerson]

I am the IT director at a large automotive facility, we
currnetly have approx 35 xp pro based computers on our
network. My situtaion is that we carry 7 different auto
manafacturers and they use different connection methods,
I have a 3mbps DSL and a 128k T1 on the network. Both use
totally different IP, SM, gateway, and dns
configurations. I need to have each pc able to connect to
both of these lines and I cannot seem to find a way to
get this to happen. I have added the additional ip
configurations into my tcp/ip properties and it either
jamms up the dsl or the t1. I am wanting to use the dsl
for the majority of the net usage and the T1 just for 2
sites in paticiular, if you are not on the T1's Ip config
you cannot access these 2 sites.. Any advise.. I would
greatly apperciat any assistance.. Sincerley Roger

Roger,

The static route table is used to provide directed routing to multiple subnets.
<http://www.microsoft.com/technet/community/columns/cableguy/cg1201.mspx>
<http://linux-ip.net/html/tools-route.html>

Assuming that you can define those two T1 connected websites as subnets /
individual ip addresses, this is doable. The DSL and T1 lines each have a
gateway. The DSL line is the default gateway, and you add entries for the two
T1 websites using the T1 as the gateway.

I have read and reviewed the info, seems real confusing
any other methods to do this, or am I just needing to
look at it in a different fashion? info on both pages
goes over the format of the routing, but doesnt explain
enough on how to accompolish what I need to do?

Roger,

It's a bit arcane the first time you see it, you just have to do it once and
you'll see. I'll walk you thru it.

There's no gui to edit the table. :-( You have to edit it line by line.

Pick a computer that works well with the DSL line to the internet as a whole.
We'll use that as an example.

Please provide ipconfig information for that computer.
Start - Run - "cmd". Type "ipconfig /all >c:\ipconfig.txt" into the command
window - Open c:\ipconfig.txt in Notepad, copy and paste into your next post.

Please provide static route for that computer.
Start - Run - "cmd". Type "route print >c:\route.txt" into the command window -
Open c:\route.txt in Notepad, copy and paste into your next post.

And what are the ip addresses of the T1 gateway, and the hosts behind the
gateway that you need to access?

Chuck

Last is the ip range of the site that I only want to
access with the t1 = 63.90.86.0-255

Thanks for your assisstance, CHuck

<SNIP>

Roger,

This is an interesting situation. I think a few additional questions are in
order.

What else is on the 205.190.22.192/26 subnet with the T1 line? How does that
subnet connect to your main subnet 65.40.217.0/25? Do you have the two subnets
connected - or are you running two separate subnets?

Your original post said "T1 just for 2 sites" - did you mean two websites
(hosts), or two separate subnets?

Do you have a computer currently working with the sites on the T1 subnet (as
rogerlt does with the DSL)? The IPConfig and Static Route from that might help
explain this a bit easier.

If the 63.90.86.0/24 subnet at the other end of the T1 just contains two hosts
that you're interested in, you can put those two hosts in a static hosts file,
and install the file on each computer.

If the 63.90.86.0/24 subnet at the other end of the T1 is an actual domain, with
their own DNS servers, you're going to have to setup your own DNS server, and
have it feed off 204.117.214.10 and 198.6.100.53.

Besides the DNS issue, we're looking at three static routes to be defined
somewhere (details to be determined):
205.190.22.192/26
63.90.86.0/24
198.6.100.0/?? (probably add to your DNS server, to point to the other DNS
server)

I have a feeling you're going to need a network consultant before this is over.
But I'll help you with this as long as possible.

Cheers,
Chuck
