Hi,
I have a Cisco 800 series ADSL router (i think it's an 837). It's an old one from work so i don't have much documentation or support with it.
I want to configure it for my home ADSL, preferably using the CLI.
Could anyone give me any info on just simply getting the ADSL up and runnning and then where to go from there ?
What the correct config-register setting is?
How to either clear current config or reset to default settings.
kind Regards

Hi
Normal configuration register setting value is 0x2102 if you want to go for a factory default then change the same to 0x2142 and then do a reload.
once you are done with the reload it will get u the default config prompt wherein you can change the registe value to 0x2102 and save the config.
Another best option is execute write erase and reload (dont save before reloading).
Relevant config for ADSL :
interface ATM0
no ip address
no ip directed-broadcast
no ip mroute-cache
no atm ilmi-keepalive
pvc 1/150
encapsulation aal5mux ppp dialer
dialer pool-member 1
!
interface Dialer0
ip address negotiated
no ip directed-broadcast
ip nat outside
encapsulation ppp
dialer pool 1
dialer-group 1
ppp pap sent-username
!
ip nat inside source list 101 interface Dialer0 overload
ip classless
ip route 0.0.0.0 0.0.0.0 Dialer0
no ip http server
!
access-list 101 permit ip 10.0.0.0 0.255.255.255 any
dialer-list 1 protocol ip permit

Wouldnt you just need a standard access list to nat not an extended one, ie access list 1 permit 10.0.0.0 0.255.255.255 !!

We can't give you now for what your asking.... We have to little information.
First make sure you know how your ISP is setting up your ADSL connection. is it by dhcp ? (layer2 mac assigned) and what are the pvc number of your ISP?

Hi,
I used the config provided and looked up the ADSL info for my ISP, PVC etc. and enetered it. It doesn't seem to work.
do i need to configure the inside ethernet interface at all?
also i couldn't ping from the router it said protocol not supported.
Any help gratefully appreciated.

Hi Mac
Try configuring an ip address under your ethernet interface and also make that interface as your NAT inside interface.
once you are done with that you can try again pinging some external sites and check whether your getting connected to the outside world..
Try the below mentioned config and check whether you are able to get connected.
interface Ethernet0
no ip address dhcp
ip address 10.1.1.1 255.255.255.0
!
no access-list 101 permit ip 10.0.0.0 0.255.255.255 any
access-list 101 permit ip 10.1.1.0 0.0.0.255 any
do clear the nat translations before you start trying to get connected.
you can use this Command to clear up the same clear ip nat translations *
