I don't understand your config: you have a desktop connected to the
Internet via ppp: this desktop has a NIC (eth0) on which your laptop NIC
is connected and you try to get Internet working on your laptop using
your desktop as a gateway. Or is there a hub to which both desktop and
laptop are connected?

In the first case (connection NIC to NIC) you need a cross ethernet
cable, in the second case both ethernet cables are "straight" (don't not
the exact word).

What is the proxy server you refer to?

The evolution request has been done from the desktop, not from the
laptop. Am I right? Packets are dropped because port 110 is not allowed
by the script, but, up to now this is not the problem.

The first thing is to explain your exact config.
