I've a Cisco DSL router 857 and a Cisco ASA placed behind it. I want to configure the Cisco DSL router in Bridge mode so that the Cisco ASA gets the Public IP adres.
I hope that someone can help me with this issue. An example with code will be highly appreciated.
Thanks.

no ip routing
interface atm 0
no ip address
interface atm 0.1 point-to-point
pvc 8/35
bridge-group 1
interface vlan1
no ip address
bridge-group 1
bridge 1 protocol ieee
Note: this won't work if ISP is using "routed 1483" or "PPPoA". Will work with "bridged 1483" or "PPPoE".
Hope this helps, please rate post if it does!

I have a very similar situation but my ISP uses PPPoA.... any ideas what would the config be for that situation please?
Thanks

dear p.bevilacqua,
My connection is PPPoA :-(

Sorry, PPPoA is not bridgeable.
You must then have the public IP in the router.
Actually an 857 does most of the things an ASA does. The most noticeable lack in the 850 series, is QoS.
