Hi

I have a network made of 3 subnets - 96,97 and 98 - 97+98 being subs of 96.
When I give my Redhat 7 box an IP number from 97 or 98 it can ping within
that subnet but not outside - if I use a 96 number then everything is ok. I
have set the gateway correctly each time....any ideas?

Cheers
N

I suspect there might be a problem with the nodes on the network but I can't
be sure as you didn't give any numbers, but lets assume the following:

Network Address: 192.168.96.0
Subnet Mask: 255.255.253.0
Network Numbers range from: 192.168.96.1 ---> 192.168.98.254
Gateway address should be something like: 192.168.98.254

I know that when we were looking at a ATM deployment, we had to create a
number of aliased gateways on the router to allow clients to think that they
were operating in a standard 255.255.255.0 network when in fact they were
operating in a 255.255.253.0 network.

If you can provide the values that you are using, you can hide the network bit
at the front :), then we might be able to spot the problem.
