Why Traffic Forwarding Fails if the NAT or QoS Configuration on a Physical Interface Is Modified After Dialup Succeeds?
This problem occurs in the following situations:
In RS-DCC, the dialer_bundle-member command is used to specify a dialer bundle for the physical interface.
In C-DCC, the dialer circular-group command is used to specify a dialer circular group for the physical interface.
To resume traffic forwarding, terminate the dialup connection and redial to establish a link. After dialup succeeds, do not modify the NAT or QoS configuration on the physical interface.
