You might not get a valid route from the PPP server or you need to add the 
following to /etc/ppp/ppp.linkup

<yourlabel>
	 shell route delete default
	 shell route add default -interface INTERFACE

to use the interface instead of the destination IP address.
You can try this manually after PPP has established a connection.
