Alain,

  It is called "NAT" - Network Address Translation, and it has to be "enabled" 
and configured on the router so that it knows to translate the 192.168.X.Y 
address(es) which are Private Network (not routable on the internet) to 
"public" routable addresses - EG the 213.51.175.90.  How you configure and 
set it depends upon the router - Cisco, Netgear, Nortell, Netopia, etc...

If you configure NAT and tell it to map your private (192.168.2.X) addresses 
to the public of 213.51.175.90 it will all start working (from both sides).
