This is what I thought - and is how my machine is configured. I have in
/etc/ppp/options the following;
crtscts
modem
defaultroute
asyncmap 0x00000000
mru 576
mtu 576
And the defaultroute makes pppd add & remove the default route when the
link goes up and down (it took me ages to find this!)
The interesting thing is that if I ping an IP address which I know is not
local when the PPP link is down, the Linux box says:
ping: sendto: Network is unreachable
I'm a bit confused here! Does this work for anyone else?
Cheers,
Marc
