these patches that I talk about are for servers, to automaticly add a
network route for a client's network... of course I now run gated which
makes this unneccessary as it will automaticly add the network route when
it sees the "remote" router... i.e.
+--------------+ +-----------------+
| Server | | Client |
| 192.168.0.30 +-----+ 192.168.3.0/24 |
+----+---------+ +-----------------+
|
+----+---------------+
| Internet via slirp |
+--------------------+
this is what I use to connect a friends network to my network... which
is then connected to inet...

this is never needed... the closest is possibly adding an alias to ppp0...
but I don't think that would work to well... you would want to add the
aliases to lo0 before ppp0...

about (1)... I'm not sure how to do that... I haven't set up natd (that
uses divert sockets) or iijppp's alias mode (you'll probably have better
luck with this) to do address translation...
but on (2), pppd should automaticly negotiate the ip addresses and configure
the ppp0 appropriately... it does it when I use the stock pppd with the
following command line:
pppd asyncmap 0 defaultroute cuaD00 38400
and this is with an empty /etc/ppp/options file... it will automaticly
configure the ppp0 with the ip addresses of both ends... and these change
almost EVERY connect...
hope this helps... ttyl...
