I set up 2.1.0 as a ppp server for one dialin client using pppd. things
work fine for a while, but then the routes get messed up on the server.

after i connect and things are running okay (the pppclient route is
properly
setup, i can do echos, http acces, etc from the client), my routes look
like
the following. pppclient is my statically assigned IP address for my
client.

after a couple of disconnects and reconnects the pppclient turns into
this dangling
route:

i've tried a bunch of combos in the /etc/ppp/options file, including
with and
without proxyarp. similarly. i've tried kernels with and without the
GATEWAY
and ARP_PROXYALL options. as well, i've tried various entries in the
/etc/gateways
file (as per man -s 8 route). all combos end up with this strange
condition.


any help will be very much appreciated.

thanks.
