DOCSIS 3 Cisco IOS Router

Hey everyone,

I'm moving into a house that has Comcast/Xfinity for internet. Since I am studying for my CCIE I'll need to set up some pretty weird port forwarding/NAT rules on my router so that I can access everything from work/the road. I'm already experienced with IOS and figured it would be easier than having to learn DD-WRT or Tomato.

Do you all know of a Cisco router that supports DOCSIS 3 (or whatever the requirement is for a Comcast cable modem) so that I could use it as both a cable modem and home router? I'll be using Ubiquiti wireless APs so all I need is a router/modem that I can use. I'd also prefer multiple gigabit ports but at worst one port would do and I would just use a cheap gig switch.

I'm looking for something similar to the 841 that is small and quiet but still runs IOS so that I can leverage my professional experience on my home router :) My whole lab is virtualized and silent and I'd like to keep that streak going. I'm looking to keep it under about $100 but willing to go up a bit if necessary to hit all of the requirements above. For some reason I'm having a terrible time navigating Cisco's site to find the product info I need so I'm bringing it to you all for some input/advice.

Thanks for any advice you may have!

    Also... I could've misunderstood whether or not DOCSIS 3 is a requirement, I know there are a breadth of DOCSIS 2.0 IOS routers out there I could snag for cheap.

    Why not just use a regular old DOCSIS 3.0 cable modem to an ethernet WAN interface on any cisco router of your choice?

    Just put the Comcast modem into bridge mode.

    Thanks... after some more googling that seems to be the best way. I just don't like having devices in the network that I don't control. Guess that's something I'll have to give up on the consumer side for now.

    I'm a Comcast customer as well, but I've always just purchased my own modem. I never use theirs. Something like the SURFboard SB6121 is DOCSIS 3.0 compatible and not too expensive at around $50-60 depending on where you look.

    I'm actually looking at picking up a Cisco 892 to setup in my own home network. I've been running DD-WRT on an old Cisco Linksys E900, and it does the basics, but I'm working on my CCNP now, so I'd like something to get a little more practice on.
