Esta receta permite realizar un tunel ip ppp GRE a través del router adsl
para acelerar la conexión y poder realizar más conexiones TCP de las que el
router permite.

This recipe allows you to bypass your thomson SpeedTouch 510 Nat mechanisms
speeding up your internet connection doing work on the host instead of the
router. Also allows more than 300/400 concurrent tcp connections which seem
to be the limit the adsl router can handle. This limit is easily hit with
p2p programs for example.
