It doesn't make any sense to change 'routing' when you are on the
same broadcast network with both addresses.  That is, the IP
handed back for the PPTP endpoint is going to have an address
within the same netmask as your ethernet card so there is no reason
to prefer it, and if it did, you would need an exception for the
source/destination of the tunnel (and at both ends...).
