Hi!
On my Cisco 1812 router PPPoE is terminated on Dialer0 interface. Every day ADSL link is flapping:

usual configuration:
! interface Dialer0 description ADSL_DATA ip address negotiated ip mtu 1420 ip nat outside ip virtual-reassembly encapsulation ppp ip tcp adjust-mss 1420 dialer pool 1 dialer-group 1 no cdp enable ppp authentication pap callin ppp pap sent-username jdsfdshfsdf password 7 dfs78df78sd end
What could be the problem beside poor coper wire quality? Is it possible that there are no any interesting traffic for certain amount of time which results in terminating connection? I have dyndns updater in my LAN so it should generate some IP traffic non-stop. Can I use some command to nail my connection to be connected non-stop? Thanks.
