Hi
does Cisco 877 router support DSL (not ADSL?). i have tried connecting a dsl line and cant get ATM interface to come up - username and password are conrrect.
alternative option: Can i get cisco 877 to form a ipsec tunnel using LAN port (not dialer interface) ? basically i want this 877 to act like asa 5505 where i can connect a LAN cable coming out from DSL router

The 877 should be ADSL, not SDSL or VDSL.
xDSL and DSL are just generic terms to encompass all variants.
Do you have any details from your ISP, other than just the username and password?
Typically, they will also provide info such as the authentication type, encapsulation type, ATM VPI/VCI details (if it's PPPoA), primary and secondary DNS etc etc
Please post router config too, including 'show ver' output to verify the part number
You'll need the right IOS in order to provide IPsec functionality. Again, the 'show ver' will help there.
To clarify, do you have an ASA5505 and another DSL router as well as the 877? I wasn't sure.

If you can paste your Dialer and ATM configurations it would be a start to get you up and running.
Should have these basic settings.

Hi Mike shillings,
i have pretty much the same config as above.
interface ATM0/1/0
no ip address
atm bandwidth dynamic
no atm ilmi-keepalive
pvc 0/35
dialer member pool 1
!
!
interface Dialer1
description ADSLhwic1
mtu 1492
ip address negotiated
ip nat outside
ip virtual-reassembly in
encapsulation ppp
dialer pool 1
keepalive 300
ppp chap hostname @att.net
ppp chap password 0
I was just wondering because it a DSL conenction would the above config work ?
Also this is an alternative option. i was wondering if i could you the cisco 877 router for ipsec for LAN port instead of xDSL ? basically dont use DSL (atm or dialler) and use the LAN port for ipsec termination, is it possible ?
Thanks
