Have a Cisco 831 DSL router pulled from working environment. I've tried a number of CLI entries to get the router to simply connect to the Internet with no success. At one point, I could ping Internet provider gateway and DNS server. I know more than what "not being able to connect" implies-yet I obviously am overlooking a simple matter. Getting the router back to how they are shipped new for CRWS (web setup) is fine with me. I can build on that. Following is running-config, sh version, and proof that web setup files are all present in webflash. I have stripped this running-config to nothing except an ethernet address to be able to communicate with the router over IP on my LAN. The DSL information is as follows:
I switch the Embarq DSL modem to run as a bridge. IP addresses are assigned via DHCP. Modem is running what appears to be proprietary encapsulation ENET ENCAP. (I've never switched this to RFC 1438 yet, when trying to set up router.) Multiplex is LLC, VPI 8 and VCI 35, ATM QoS Type UBR

Hi,
Try this:

ip address dhcp
ip access-group 115 in
no ip proxy-arp
ip nat outside
ip route-cache flow
service-policy output QUEUING

ip accounting output-packets
ip nat inside
ip route-cache flow
standby ip 192.168.X.X

!
ip nat inside source list 5 interface Ethernet1 overload
access-list 5 permit 192.168.1.0 0.0.0.255
access-list 5 permit 172.16.0.0 0.0.255.255
access-list 5 permit 10.0.0.0 0.255.255.255
If it does not work try:
debug dhcp
(ter mon)
to see if you get an IP from the ISP
