At times when ISP drops an internet connection, it is needed to put the router in bridge mode so that the public ip address can be directly assigned on the inside firewall (any brand).
So you can put a cisco router in bridge mode this way;
bridge 1 protocol ieee
int fa0/0 <–connected to ISP (change interface accordingly)
no ip address
bridge-group 1int fa0/1 <–connected to ASA (change interface accordingly)
no ip address
bridge-group 1
Keep up the good work.
Hi,
Will this work if your connection to the ISP is a T1 (or any other non-ethernet encapsulation)?
Thanks,
Nick
Yes you can.

Will you still be able to use acls in bridge mode?
Yes you should be.

Thanks man,what is the feasible way to access the router from LAN( through f/w) after youve done bridging.
You can always have IRB (Integrated Routing & Bridging and access through that, it provides you access, as well as does the bridging.
