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!
