(IPTables) old dog needs some help with a dual-homed debian (woody) system

(N) WIRELESS (H) ETHERNET (x)
Notebook <----> linux-dev <-----> linux-fs
w/ wireless w/ wireless IP 10.0.2.1 ethernet
card IP: 10.0.2.2 & ethernet IP 10.0.1.12 IP 10.0.1.9

NOTE: THERE ARE NO wireless HUBS (that stuff that we can buy at
stores).

The last machine (x) is ONE sample machine on the ethernet hub, I
picked it to explain my problem better.

(N) can ping (H) and vice versa. ANd ofcourse, the ethernet network
has been working for a while now.

But (N) cannot PING anything other than (H) and (N)'s IP is assigned
manually.
(N) is a windows PC with netmask set to 255.255.0.0 and the gateway
to 10.0.1.1
And yes, the OTHER machines can ping each other quite well over
othernet (10.0.1.x).

I tried all possible combinations of netmasks, but no luck.
In my youth :-) I used to tell IPCHAINS to ' -j FORWARD ' and that
would (I think) have done the job...

Please let me know what I neeed to do.

Thanks in advance...
