Hi Emmanuel,

You are french, aren't you? :-)
Imagine the following scenario :

MachineA (192.168.0.1) --- (Private address 192.168.0.254) GatewayA (public
address 68.2.3.4)   --- INTERNET---- (public adress 68.2.3.5) GatewayB
(192.168.1.254) --- MachineB (192.168.1.1)

Data are encrypted between gatewayA and B. MachineA wants to communicate with
MachineB. Then the ip packet header looks like : 192.168.0.1, 192.168.1.1,
options, data

When the packet arrived at GatewayA, the original ip packet header are
encapsulated and crypted in a new one, it looks like :  68.2.3.4, 68.2.3.5,
original ip packet crypted.
When GatewayB  will receive the packet, it will decrypt it and transmit the
original packet to MachineB. So nobody can see the sender and the receiver on
the internet...

I've read on a site that if I want to  achieve this  I have to use ESP and AH in
tunnel mode. In my case, it's much simplier because I just want to encrypt my
data between my laptop and my gateway to secure wireless network. But it
doesn't work.

Anyone can help me? I didn't resolve the problem of downloading too. I've notice
that some sites are not accessible from my laptop even if they are accessible
from the gateway (with firewall off).
