Also was wondering, with the configuration below, if i have the
options.ttydx file and a ~username/.ppprc file and a user calls into the
a given node that has a options.ttydx line it uses the ip address i have
in the options.ttydx file and not the ~username/.ppprc file how is this
fixed so that i can have a ip address on the modem so that if a user
dials in and they dont have a ~username/.ppprc file they get they get the
modem ip and if they do have have .ppprc file they get there own static
ip address?
