After rebooting my Mandrake 8.0 server machine, connection sharing no longer works, both from my Windows 2K client, as from my Mandrake 8.0 client (the same machines, different partitions). I'm sure that physically the network works fine (I can do pings from both sides internal to the network, I can do ssh from my client to the server, and I can use VNC-client from my windows machine). However, I cannot ping from the client to an external address (e.g. www.yahoo.com), although the address got resolved correctly. I can ping to the external address from the server (I have an ADSL-connection, masquerading enabled), do some browsing, sending this email, ... I also verified that the ping got over the pppoe connection (ifconfig gave extra transmitted packets). SAMBA isn't working also (it was before rebooting).
here's the output of ifconfig:

eth0 connects to my provider (ADSL), eth1 connects to my internal network.
Here's the output of netstat -nr:

However, I did try to set security settings to medium (Mandrake Control Center), and I tried to install the firewall (however, because I gave my CD to someone else, I couldn't install the necessary packages).
Another strange thing, is that I can't issue iptables -L, it gives the following error:
iptables v1.2.2: can't initialize iptables table `filter': Module is wrong version Perhaps iptables or your kernel needs to be upgraded.Any help is very welcome, since this is a very frustrating situation.
Thanks in advance,
