Just so.

Interesting. I don't fully understand how to make the route(8) command
do the right thing but I took your advice and did "route del
default".  And the laptop->adapter->modem->dialin->ppp->internet
process is working.  And the laptop still talks to my localnet as it
should.  I could have posted this from the laptop but I like to have
my Usenet interaction logged on my main machine do I didn't.

Me too.  And I have masquerade working and can do it that way.  I just
wanted have this dialup functionality available, too.

Thanks for your help & best wishes,  Old guy.
