Please don't lose patience with a poor grandfather who spends the
wee hours of the morning trying to learn something about Unix.
I have never seen a professionally set up system (which would explain
a lot) and I learn by trial and error (mostly error).

I was not typing about route_loopback.  The following is the
'netstat -rn' from 205.150.43.2 running the new routed.

The **** item is the one added by both gated and routed.  For
that reason I assumed it was necessary.  Am I wrong? They also add
the broadcast routes, which also seem to be necessary. I don't have a clue
how to manually add the one above:-)

You will note that the default route to 205.206.213.3 has been
deleted by routed.  

Before the ijppp call that established the above, the pertinent routes were
default		205.206.213.5
205.206.213.5	205.206.213.111
206.206.213.111	127.0.0.1

Most traffic 'starts' with a DNS lookup.  If my
primary server was in 205.206.213.0, I believe that things 'might' start up
OK, but my primary DNS server is 198.53.64.7, run by my ISP's ISP,
and without the default route, the DNS lookup is not routed to tun0
and ijppp does not make the call to establish the connection.

I hope this clarifies my previous comments.

Regards,
Tom
