connecting 2 offices via T1???

I have two T1's installed to each office and cannot get MCI to fulfill their
promises of assisting in making the two offices look like an intranet.

What is required to make a T1 on 10.1.0.1 talk to 10.2.0.1 and behave as if
it is one intranet?

I had ISDN serving each office and they requested the two offices look like
one.
MCI sold me a bill of goods (very expensive) to get 2 T1's installed and
then they would assist with the routing. Now, they cannot remember the
conversation and want to charge to come out to help.

The computers within an office all network just fine. And when they are
connectd to the ISDN lines - we get to teh outside world just fine.

I'm not understanding what how hook the routhers into the T1 modems and make
then bridge the two offices.

MCI gave me all the data I'm sure I neeed to set up the routers within the
office to connect to the outside world but what other devices, software or
configuration do I need to connect to the outside world and also route
traffic bewteen the two offices acting as an intranet?

What types of quick courses are available to get this type of training?

Looks like all you need is a router. but not one of those cheap
internet ones. its got to know where all the computers are on each
network so it can forward there requests.

You will not be "bridging" the two offices, they will still have to
cross the router. You should simple be able to plug them both into the
router and be done with it. Also turn off any firewalling.

========================

There cannot be one router. These 2 offices are 10 miles apart. We have to
plug several machines into some device in each office that will allow then
to connect to the T1 and communicate with teh outside world.

So how do I get the one office to "route" traffic to the other office? There
obviously has to be routing done from one to the other - so doesn't that
take two routers?

The way I see it - we have to plug one device into one T1 modem A and
another into the other T1 modem B. Something on side A has to "route" to B
and something has to route traffic to A. Doesn't this imply two routers? And
therefore seetings in one need to "route" traffic to the other device so
these two offices see each other as one intranet.

Didn't MCI set up/sign a contract? I went through a similar situation about
two years ago, then I went back and made sure about all the terms we agreed
to and found it in writing. BOOM they had to come fix it. Just a thought.
If , not, well sorry, but I have no idea how to fix it, but you would
probably get much more helpful info over on a Cisco newsgroup. P.S. GET
THAT STUFF IN WRITING FROM THIS POINT ON!!!

Best of luck, I feel your pain!

You will need to setup some form of VLAN probably with some
form of IP tunneling protocol. Each of your routers would be setup
as follows:

Router A.
Internal Adaptor 10.1.0.1
External Adaptor 1.2.3.4
VLAN Adaptor PTP to 5.6.7.8 for Subnet 10.2.0.0

Router B.
Internal Adaptor 10.2.0.1
External Adaptor 5.6.7.8
VLAN Adaptor PTP to 1.2.3.4 for Subnet 10.1.0.0

Thus your router will handle it for you. Of course, both routers
need to support VLAN and the like - I'm presuming from the
ng that they already are so you should have no problems.

An idea I always tinkered with but never implemented was
(perhaps someone wiser than me could provide feedback)
could you just do it with IP forwarding and routing??

eg from our earlier example;

Router A. Allows outgoing 0.0.0.0 NAT traffic.
Allows incoming traffic to local LAN from Router B.

and the reverse for router B.

Then a route to the remote net could just be set with
route add default gw or some such similar wizardry.

The VLAN option is probably the ideal though.

Hope this helps,

Dave.

MCI is notorious for that kind of nonsense.. I tried to buy a T1 a
few years back. After all was said and done, I had the installation
crew on my doorstep and the sales dept. STILL hadn't provided the
complete - with pricing - contract. a month of 'we'll fax it right
over'. Ha.

Needless to say, I escorted the installation crew from the premises
and cancelled the contract. They tried billing it anyway, but I had
personally warned the comptroller that they'd likely try something
ELSE sneaky and underhanded, so they didn't succeed.

As I see if, the answer to your problem depends on EXACTLY what you've
purchased. Do you have 2 T1 connections to the internet, or a
dedicated T1 between the offices? If the former, set up a linux
system running iptables and VPN at each office. If the latter, you
don't need the VPN, just a good flexible router package.

Now that I think about it you are correct. What I suggested would work,
but it would send questions or ARP requests across the T1, and there is
no need for that. That would be bridging. 1 router on each end would
perform much better. That also eliminates my thought to use a switch
since that would be forwarding DHCP requests and there would be no
logical sense as to which addresses were where.

With this new breakdown, those inexpensive broadband routers will work.
Not to mention that they can handle t1 traffic no sweat.
