Eamon Roque asked:Nonetheless: what does your authentification process look like? Do you require the host to authenticate itself, do you agree on a protocol ( usually in /etc/ppp/options )?
The following is a list of uncommented things in /etc/ppp/options:
auth
crtscts
modem
proxyarp
lcp-echo-interval 30
lcp-echo-failure 4
noipx
Everything esle in this file is commented, hence not operative.
