Hello

use the following document

http://www.cisco.com/en/US/tech/tk175/tk15/technologies_configuration_example09186a0080093e5f.shtml#configs

to implement IRB correctly you need also:

bridge ip protocol ieee

bridge 1 route ip

also to make a bridge also the lan interfaces or the Vlan1 needs to be associated to bridge-group 1.

But to be noted if you do so NAT is not needed or possible.

So you need to think about what you want to achieve

Hope to help

What is your config supposed to reference? Are you connecting to a DSL provider? What type of connection is this? Did they assign you the IP address? Do you have some other device that is connecting to the router on the provider-facing side?

The config doesn't look complete, but it's hard to tell you what's missing without knowing what you're connecting to.

HTH,

John
