1. The dialer user under the dialer interface is mandatory for dialer bundle.
2. The ADSL account and password are provided by the ISP, and the authentication mode (PAP or CHAP) shall be the same as that configured on the DSLAM. You can execute the debug ppp command to figure it out.
3. In the case that the Internet is reachable, but the user cannot open webpage after the NAT, you shall configure tcp mss 1400 on the intranet and Internet interfaces.
