Ok, it almost works. ;-)
The "set device" line barfs in my version of user ppp; I changed it to:
set device localhost:1234
and ran "ppp -auto tcp-client" on that machine.
Now, I have to run /etc/ppp/secure-connection by hand and the connection
works.
Two questions:
1) (A more basic PPP question) I can't see any machine other then the
other end of
the PPP connection. Yes, I did enable IP Forwarding. Some other
config problem that
I might have overlooked?
2) I'd like to automate the process. My hope is to get something going
like the on-demand
dialing function, where packets going to the remote network cause
the ppp connection to
happen. Am I dreaming?
If I can figure this out, and do it in a nice way, I'm only more then
willing to package the whole
thing and donate it back to the project.
Thanks,
Gerald
