I am doing a migration of all our ADSL routers (non-cisco) to 827 Cisco router. Until now I had no problem at all.
But with one I have a routing problem :
This is my config :
Cisco827#sh run

As you can see , quite an easy config which I did on every router. But on this setup I can ping from my laptop (connected to the router) to 10.16.5.1 and to the WAN IP adress. But I can't ping to the WAN Gateway 194.78.209.1. And on the router I can't ping to my WAN interface and to my WAN Gateway.
Alle the WAN IP addresses and VPI/VCI are OK because I copied them from the non-cisco router.
Probably I am missing something but I can't think of what.
Thanks in advance for the help.

Something I forgot : I have a good connection to the DSLAM (CD led is green)
But if I do a debug atm packet :
I get ATM0(I): VCD:0x0 type:0x0Inactive or not configured VCD length:0x38
I hope this could help you

first, the "encapsulation ..." command is missing in the config. Also you need to know what kind of technology that adsl line is configured for.
Is it RFC1483 bridging or routing, RBE, PPPoE or PPPoA etc.
Once you have that information, here is the same sample config for that
For RBE
http://www.cisco.com/warp/customer/794/827rfc_6400rbe_1.html
For PPPoA/PPPoE
http://www.cisco.com/cgi-bin/Support/browse/psp_view.pl?
p=Internetworking:PPPoE__PPPoA__PPP_over_Ethernet__PPP_over_ATM&viewall=true
For RFC1483 bridging
