 Hello,
 How is it possible to share internet connection (like in Windows
 connection sharing)? I have two networks cards in one computer and one
 in another. Two computers connected through this networks cards.
 Besides, it would be grate, if internet will work in Windows. Thank you
 for help in advance...

different list mail and this way mix up threads.

To your question: choose one of the PCs as the router, the on connected
to the net. On this one you have to enable IP forwarding, see
/etc/sysctl.conf. You too have to enable NAT/masquerading by creating an
iptables rule like

iptables -A POSTROUTING -o ppp0 -j MASQUERADE

where here ppp0 is the outgoing internet device. Obviously the router PC
itself has to be able to connect the internet. On the other PC which
uses the router PC you have to set the router IP as gateway and set the
DNS servers of your ISP in /etc/resolv.conf.
