Hi all.
I have a customer that gains internet access, using a Cisco 827 router, configured as pppoe
client over an ADSL line.
He needs to automatically disconnect/logout the pppoe client, when there isn't activity.
I tried, w/o success, using the "dialer idle-timeout" parameter on the Dialer Interface. The pppoe client logins itself, without the needing of the "interesting traffic" of the dialer_list/dialer_group statement.
Any suggestion will be appreciate.
Efrem.

if his sole internet purpose is web browsing.........
i'd make only http and dns "interesting" traffic so that when the client sits down and brings up a browser, then the link will come up.
****but if he uses an AntiVirus that checks for Automatic Updates or Windows Update, then DNS will cause the line to come up when no one is using the pc.
access-list 101 permit tcp any any eq 80
access-list 101 permit udp any any eq 53
dialer-list 1 protocol ip list 101
****then again if you figure out the resolved IPs used for Automated Updates, you could deny them in the acl referenced by the dialer-list (so that the link only comes up as expected).

Thanks for the answer, but they aren't the ethernet attached clients that rise the link: it rises also with no powered on clients.
