DSL and a 2620xm

[Maverick8673]

I have a cisco 2620xm router and what I would like to do is connect my home DSL to it. I am hoping to be able to use the 2 ethernet ports in the router and not have to buy a ADSL wic. Never have done it this way, so first question is there a way to do this, have one ethernet interface recieve DHCP from the DSL modem, and use the other ethernet interface for the private side of the network? Any assistance would be greatly appriciated.

Thanks,

ya that will work fine. youll just need to leave the modem in bridge mode and set up your router as follows. im actaullt using a 2514 so your router should be better off in this situation..

ip subnet-zero
!
no ip bootp server
vpdn enable
!
vpdn-group 1
request-dialin
protocol pppoe
!
interface Ethernet0
description ADSL WAN Interface
no ip address
ip route-cache flow
pppoe enable

no cdp enable
!
interface Ethernet1
description LAN Interface

ip nat inside
!
interface Dialer1

ip mtu 1492
ip nat outside
encapsulation ppp
ip route-cache flow
ip tcp adjust-mss 1452

Thanks for that help got a question, what IOS are you running? The VPDN command protocol pppoe is not taking I am running 12.2(27) c2600-ik9s-mz.122-27. So the question is, is it IOS related or something else? Thanks again.

Are you entering VPDN enable first?

 

[Maverick8673]

Yes, was doing that, I went ahead and put a 12.3 IOS on the router and it took the programming. the only issue now is that the virtual interface is going up and down.

 

[plshlpme]

im am using a 12.2T ios on my 2514

the only other thing i can add to this at this point is that your config is probably good and just verify that your username and passowrd are correct.
the other possibility is that your isp may use chap as the authentication instead of pap ???

Here is a capture from the console showing the error I get with the sh run. any clue as to where I went wrong?

here is some config i found on dslreports.com for a bellsouth user, the only difference i can see is that your not including the domain name on your chap login... and that is required because your isp will route your login based on the username... ie a wholesale company can still use the physical local loop to provide internet to you. say it was company ABC.. your login would be xxxx@abc.com and then you would be routed to that isp...


ppp authentication chap pap callin
ppp chap hostname xxxxxxxxxxxx@bellsouth.net
ppp chap password 7 144E465A5C557A73
ppp pap sent-username xxxxxxxxxxxx@bellsouth.net password 7 10175D4855464253
ppp ipcp dns request
ppp ipcp wins request

the above should work for you if you put in your username and password correctly....
