I have a class b network with 26 bits of masking with e0 on my router belonging to that subnet. When I set up a class c private IP address NT box I can't see the freaking class b/26 network from it. I have tried setting static routes on the NT box using the "route add" command but I just lose more hair Of course when I give it one the class b /26 addresses it works fine. I ran in to the same problem with my spare 2500 when I gave it's E0 a class c private IP address. Am I missing some thing here or should I call A1 truck driving school?

Why don't you show us the numbers? And, is the NT box supposed to reside on the subnet attached to e0?

(BTW, do you know what "NT" means? Neanderthal Technology )

Cheers!

Sorry about that.. The class b is 158.76.237.64/26 and the class C is 192.168.0.2/24. The placement of the NT box is not as important as to why I can't ping the class b/26 subnet. I put a class c/24 address on the router's E0 int to see if my NT box was working properly

Maybe I'm getting this wrong, but just to make sure, is this what you're trying to do?

<NT>pvt net------class B<Router>

That is, are you trying to put both networks on the same "wire" (broadcast domain)?

If not, I apologize in advance

If I've got it right

Router E0-158.76.237.64/26
NT Box -192.168.0.2/24

The NT is on the same wire as E0, if this is right then you would be able to ping each other. Your on a diff network, If you create a sub-interface on e0 (the interface will have to be a Fastethernet) and give a 192 address it will work.

I'm still confused about your setup...
---------------------------------------
First: As far as I can tell, you have assigned the subnet address xxx.64(host= all 0's) to e0 on your router, this is a big nono.
-----------------------------------------

If you want to "force" two interfaces on different subnets residing on the same wire to communicate, you can set a static interface route on both interfaces. AFAIK you can't do this on an NT box, though.

Example : (Router2 would be your NT machine. However, I'm using IOS commands since I don't think this is possible on NT)

Router1
---------
ip route 192.168.0.0 255.255.255.0 e0

Router2
---------
ip route 158.76.237.64 255.255.255.192 e0

As to why you would want to do this, I can only speculate...

Putting the class b and the class c on the same wire is what I'm playing around with. This is not a permanment thing. Just wanted to see if two diffrent class and or subnets can see each other sharing a common connections on the EO side of my main router. By the wayThe x.x.x.64 is not address of the router e0 port it's actually .65.... I was showing that address just as one would show 15.0.0.0 as being a class a network. I guess what every one is saying is that a static route must be set up between both networks in order for communications to take place. I'll give it another try. Static routes can be added to the NT route table buy using the route add command.

Hi whytokayok!

I know I can set a static route using e.g.
route add 10.0.0.0 mask 255.255.255.0 192.168.0.1

The problem is you need to use an interface as a gateway instead of a next hop router (192.168.0.1 in this case). If this is possible under NT, could you please post how to do it?

Creamy,

I can add another IP address to the interface card in the NT machine but that defeats the pupose of trying to save an class b address. Other than adding a second interface card, I can't figure out any other way to do it at the moment. By the way, I tried adding a second address to my router E0 port to see if it could server as two default gateways and it locked up ...
