dialer-group 1

!--- Apply interesting traffic definition from dialer-list 1.

! -- Note: The specified dialer-group number must be the same as

! -- the dialer-list number; in this example, defined to be "1".

! -- Interesting traffic specifies the packets that should reset the idle timer.

dialer idle-timeout 600

! -- Sets Idle timer to 600 seconds (10 minutes).

async mode dedicated

! -- Allows only PPP dialup. Prevents users from establishing

! -- an "EXEC session" to the router. If the async interface is to answer

! -- different connection types (exec,ppp,slip etc),

! -- use async mode interactive in conjunction with autoselect ppp

! -- under the line configuration to auto detect the connection type.

peer default ip address pool dialin

! -- Clients are assigned addresses from the ip address pool named "dialin".

ppp authentication chap pap

group-range 33 56

! -- Modems 33 through 56 are members of this group async interface.
