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,

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
