network problem: internet sharing

[Keith Antoine]

I seem to have given may an incorrect version of my internet sharing problem.
The problem is NOT that I cannot share my machine with daughters downstairs 
machine, but that I cannot share theinternet connection. This does not entail 
any file sharing on either machine and is normally done both in XP and in 
Mandrake 9.x via aGUI interface. This has always worked in the past on may 
other machines that i have installed. However not this monster.

OUTPUT of ping to downstairs machine:
[root at dhcp-817-6 kantoine]# ping 192.168.1.2
PING 192.168.1.2 (192.168.1.2) 56(84) bytes of data.
64 bytes from 192.168.1.2: icmp_seq=1 ttl=128 time=0.246 ms

Now if I go downstairs I cannot ping to this machine 192.168.1.1
nor can I 'see' the net with a browser. This is irrespective of the OS on this 
upstairs machine. So there is something wrong on the downstairs machine or 
the connection to this machine !! Logic dictates that. No the nic leads are 
fine as I would not be able to ping downstairs and the cards would have X on 
them.

Question what moves do you suggest that I make now, given the above.
