The only problem I see is that you're attempting to add two default routes in
inetgw:ppp.linkup - When 10.133 establishes the connection, it gets the default
and inetgw sees no point in sending packets back where they came from.

Try removing the 10.0.0.133 entry from inetgw:ppp.linkup - it's not required.
