What should i change in order to achieve one-way authentication ?
Let's suppose that router2 is the "client" which "calls" the ISP and router1 is the "ISP".
Router1 should authenticate router2, but not the opposite.
Is there a way i can have a serial connection between these 2 routers using a dialer-on-demand scenario on the 2nd router? That way the serial connection will be up/up only when there is interesting traffic from router2.
For one way authentication, "ppp authentication chap callin" on router 2 (already there) will do the job. with that command only router 1 will authenticate router 2 but not the reverse. That command with "callin" make the router authenticate to inbound call.
Now for DDR on a leased line, you can configure "interesting traffic" with "idle-timeout" in order to disconnect the line when there is no interesting traffic for idle-timeout.
So add following commands
dialer idle-timeout 600 <---10 mins
and in global config define interesting traffic using
"dialer-list 1 protocol ip permit"
to permit whole ip traffic to be allowed to bring up the line and reset the idle-timeout.
So with above config, the serial line will be disconnected if no ip traffic is passed for 10 mins.
