[Users] Hide ppp0 behind virtual ethernet device -- Is this possible ?

[mikolaj]

Hello.

I am using fedora 15 with gnome 3, whose network manager doesn't handle 
dsl connections.I have working internet connection, though some 
programs, which ask network manager if there is any connection to the 
internet, fail to work since my connection is not detected.

Is there any way to setup virtual ethernet device, in such a way that 
all traffic directed to it will be routed to ppp0 and also all traffic 
coming to ppp0 will be send to this virtual device ? This way I the 
virtual ethernet device would appear ( I hope ) to network manager as 
ordinary 'cable' connection.
