Hi,
I have applied the following configuration on my internet router my ADSL interface is up and the link protocol is also up but still is not getting an IP address and as consequence not able to communicate through it to my ISP nor to the internet. The configuration I have is:
interface ATM0
pvc 0/35
encapsulation aal5mux ppp dialer
bundle-enable
dsl operating-mode auto
bridge-group 1
exit
interface BVI1
ip address x.x.x.x 255.255.255.248
ip nat outside
Please let me know whether this ADSL configuration is alright or I need to fix anything in it.
Thanks,
Haitham

Which model are you using? Cisco 870 series??
Depending to the model you may need to create VLAN and "ip nat inside" to this interface so the Network translation may occur.
#Other than that my 878 need a DSL controller config for the g.shdsl connection. Have you created one?
!
controller DSL 0
mode atm
line-term cpe
line-mode 2-wire line-zero
dsl-mode shdsl symmetric annex A-B (your config might be different for ADSL)
line-rate auto
!
#How about the dialer interface? Have you created one to send your password and username?
!
interface Dialer1
description $FW_OUTSIDE$
bandwidth 1024
ip address negotiated
ip nat outside
ip virtual-reassembly
encapsulation ppp
dialer pool 1
dialer-group 1
no cdp enable
ppp authentication pap chap callin
ppp pap sent-username yourusername password 0 yourpassword
ppp ipcp dns request
!
# Created a default gateway to Dialer interface?
ip route 0.0.0.0 0.0.0.0 Dialer1
!
I hope it helps,
Best Regards,

...and a VLAN for nat inside?
!
interface Vlan1
description INSIDE
ip address 10.0.0.1 255.255.255.0
ip nat inside
ip virtual-reassembly
ip tcp adjust-mss 1452
hold-queue 100 out
!

Hi,
Thanks for your reply.. My router model is 2801, does the same config apply on this model as well?
I came across a configuration example for 2800 routers but it was not that detailed. I could only figure out that I need to create a BVI interface as I sent to you. Now, why do I need to create a VLAN for the nat inside?!
Attached is the configuration I prepared for my router, and my main problem is in bringing up the ADSL interface.
