Routed ppp

Yes this looks good to me also, but I have no exp of ppp. However the 
current status of the route table also suggests a possiblity as to why 
the ttl is expiring becuase it looks like the packets are going in a 
loop e.g    windows -> gateway -> int_if -> windows -> gateway and so on.  

Deletion of the default route in the table and addition of your add 
directive to the ppp config may well solve this problem :)
