OK - well let's evaluate my assumptions then...

You have something like a Netgear Wireless Router (I think they use the
192.168.0.0 network) or perhaps one of the newer Qwest supplied
Actiontec dsl modem/routers with wireless and your Mandrake box connects
with a cable to one of the LAN ports and the Mepisbox (your laptop)
connects to this same router via wireless.

With this assumption (brand accuracy not important), then they are both
'pinging' the same gateway - 192.168.0.1

With this assumption, from the Mepisbox, you should be able to ping
192.168.0.100 as well as 192.168.0.1 unless there is a firewall on the
Mandrakebox. If not, then on the Mandrakebox, type 'iptables -L' and
post the results

With this assumption, from the Mandrakebox, you should be able to ping
192.168.0.101 as well as 192.168.0.1 unless there is a firewall on the
Mepisbox. If not, then on the Mepisbox, type 'iptables -L' and post the
results

If I am to look at the manual for your specific wireless AP - (to see if
there is some setting that might prevent wireless from accessing LAN),
you should let me know the make & model of your wireless AP so I can
download the manual from the internet
