I am having an issue with Comcast.  Customer has a Comcast modem set to Brige mode.  We have a 2911 behind the cable mode with a public IP address on the outside interface of the router.  We have a couple of NAT statements on the router to make some equipment behind the router accessible via Public IPs.  It seems that, unlike a T1 or other circuit, the other public IPs are not showing up on the single interface that is connected to the router.  Anyone have any experience on getting this to work as desired?

Thanks in advance!  All replies rated.
