Hi,

ok put them back in then. I really don't understand why you get this private IP, you should provide your ISP with the debug output and ask them what is happening.

Hi,

Before escalating to your ISP, could you add 'ppp ipcp default route' together with the 2 other commands under the dialer interface. Do a shut/no shut on the ATM port and try again.

johnlloyd 13,

I have reconfigured the two other ppp commands back into the d0 interface, but will not accept the "ppp ipcp default route" command as you can see in my below input:

Router#

%LINK-3-UPDOWN: Interface FastEthernet1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet1, changed state to up

Router#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)#int d0

Router(config-if)#

%DIALER-6-BIND: Interface Vi2 bound to profile Di0

%LINK-3-UPDOWN: Interface Virtual-Access2, changed state to up

%LINK-3-UPDOWN: Interface ATM0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface ATM0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access2, changed state to up

Router(config-if)#

Router(config-if)#ppp ipcp default route

                            ^

% Invalid input detected at '^' marker.

Router(config-if)#ppp ipcp mask request

Router(config-if)#ppp ipcp address accept

Router(config-if)#

Router(config-if)#exit

Router(config)#exit

Regards,

Bob.

Hi,

this feature is only available in  12.3(11)T and 12.4 images.

I wonder how it could prevent you from being given a private IP

Regards.
