I have a Cisco 2601 router with a Docsis cable hwic installed(HWIC-CABLE-D-2). I am trying to connect this to my fatpipe so that the fatpipe manages the public IPs.  I enable bridging and when I plug into that port I don't get an IP address from the cable DHCP.

It should be noted if  I remove the bridge group and tell the cable interface to DHCP it gets an ip addres, so problem is not with cable connection or hwic

You need to issue the command "ip address dhcp" on the BVI 59 interface.

you need to set your BVI interface to get an ip address from dhcp.

interface BVI59
ip address dhcp

I just looked through your config.and something's not making any sense. Your router only has one layer 3 interface.

What is it you're trying to accomplish?

If all you want is "an expensive cable modem" then remove the "bridge irb", delete the bvi interface and you're all set.
