newbie question: suse8.2 as a router for a windowsXP machine

Hi all,

I'm new to linux and to this group, so if I'm posting
off topic I apoligize.

The problem is this:

I have a suse8.2 machine with two network cards.
192.168.0.3 is in connection with a apache router,
which has a intenet connection via a cable modem
(I share internet with a house-mate).
192.168.1.1 is in connection with my windowsXP machine.
Obviously I want a internet connection on my windowsXP
machine, but I can't get it working (It's working fine
on the suse8.2 machine).

On the suse8.2 machine I've made the following config. with YaST2:

subnetmask for 192.168.0.3: 255.255.255.0
subnetmask for 192.168.1.1: 255.255.0.0
default gateway : 192.168.0.1 (the apache router)
ip-forwarding: enabled

windowsXP config.:

ip adress: 192.168.1.2
subnetmask: 255.255.0.0
default gateway: 192.168.1.1

Now the strange thing is (to me, as a layman), that, from the
windowsXP machine, I can ping 192.168.1.1 and 192.168.0.3 but
not 192.168.0.1!

Can anyone help me?

TIA

Does the apache router know anything about the 192.168.1.0/24 network or
how to route to it via 192.168.0.3 as gateway? If not, or you have no
control over that, you will need to configure SuSEfirewall2 so your
192.168.0.3 interface will masquerade and answer for your 192.168.1.0/24
subnet.

Read through and edit /etc/sysconfig/SuSEfirewall2 and set:
FW_DEV_EXT="eth0" (assuming that is 192.168.0.0/24 net)
FW_DEV_INT="eth1" (assuming that is 192.168.1.0/24 net)
FW_ROUTE="yes"
FW_MASQUERADE="yes"
FW_MASQ_NETS="192.168.1.0/24"

and read through the rest.

Thanks a lot, that did the trick!
Though these settings make some sense
to me, I don't yet fully understand them.
Hope this comes with time.
Thanks again!
