ADSL without authentication

[s-santhosh]

The ISP is Telia, confirmed No authentication is required.

   1) In this situation does it required to configure the dialer interface.?

   2) Does it require to configure the ATM virtaul interface (atmx.x)?

   3) Do the following configurion does makes any scence

    interface ATMx.x

        ip address dhcp

       ip nat outside

        ip virtual-reassembly

        atm route-bridged ip

        pvc 8/35

          encapsulation aal5snap

4) AS Public IP, DNS, Gateway is assigned via DHCP, listed out the configurations for NAT and gateway.

    Does this works for my scenario

    ip nat inside source list 101 interface atmx.x overload

    ip route 0.0.0.0 0.0.0.0 atmx.x

I found the solution:

1)It is not required to configure the dailer interface if no authentication

2)Yes it is require to configure the ATM virtual interface

3)Yes, it worked for me

4)Both NAT and IP route is worked for me.
