ISDN router 2nd router on LAN

we have a LAN using the 192.168.x.x reserved IP address space - 

our cisco 2501 router is sitting at 192.168.1.1
and each segment is 192.168.10.1 or 20.1 or 30.1 etc
we are using static IP routes for all locations.
our local WIN95 desktops have 192.168.1.1 as the IP gateway address.

Now - how can we add an ISDN router to our LOCAL network 
	for connecting on demand to a local ISP ??

#1 - how can multiple gateway addresses be used in WIN95 ??
	I see they can be input - but how would that work ??

#2 - how can I spec in the 2501 "another gateway" for unresolved paths ??
	
any other ideas or comments on how to add a ISDN router to the network 
	as the 2nd router ??

Your description is a little vague in terms of what the 2501 is doing
right now--I'm assuming that it is not routing anything to the Internet in
the status quo.

If that's the case, the answer's easy.  Just set up a route on the 2501 like so:

ip route 0.0.0.0 0.0.0.0 192.168.X.X

X.X should be the rest of the address for the ISDN router.  The 2501 will
send stuff that it doesn't know what to with to the ISDN router, which
should in turn hand it off to your upstream ISP.

Or maybe I'm just missing a piece of the puzzle here...

tnx - the 2501 is connected to our FR network serving branch offices.
I used the 192.168.x.x so we would not have conflicts in the future.

but now - here's a question about your suggestion - 
If the ISDN router is going to get a static/dynamic
address assigned from the ISP - 
how can I also have it sit on the 192.168 net?

Isn't there only a single IP address for the ISDN router ?
for something like an Ascend P50, or Netopia, or Kentrox Pacesetter ?

Get a real router.

: Isn't there only a single IP address for the ISDN router ?

Very few do the single IP thing.  Almost all can have one IP per
interface.

If this is a serious operation, then you probably want to get something
more serious than the routers you mention...

: for something like an Ascend P50, or Netopia, or Kentrox Pacesetter ?

...like a Cisco 1004 or 1600-series.  The higher-end of the Netopia line
might be reasonable as well, though I think really you want a router
running a full blown IOS type system, and the 1004 and 1600s fall into
that category.  

If this your employer's company or are you consulting?

   Give me a compiler and a box to run it, and I can move the mail.

sorry - I forgot, since no one has mentioned it, 
I'm guessing I'll need to run NAT on the ISDN router 
to work with the 192.168.x.x local IP addressing,
and convert it to the address-space assigned from the 
dialup ISP - 
at least for testing and getting things rolling...

will the traffic from the clients ALWAYS go to the 2501,
and then get routed BACK onto the Ethernet over to the ISDN router?
So - any Internet traffic will cause a double trip on the LAN ?

BTW - in Win95 TCP/IP properties setup - 
why is there room for a list of gateways ??
