Several of us on our ISP (google fiber) forums are - having a discussion - because they supply a terrible router device and insist that we must use it, and cannot use our own Linksys/Netgear/Linux/etc device as with any other residential ISP.  They also haven't been too much help in resolving the issues we're having.  In short, the router provided has a mess of interface bugs and a bunch of broken/missing functionality.  (Yes -- fast speeds, and nonsense like half-baked port forwarding management if the forwarding works at all.)  All we're really asking them for is a way to put their router into a bridge mode so that it acts more like a typical cable or DSL modem.

Are we looking at needing a full Cisco IOS device and CCNA background?  Can Linux with a couple of ethernet cards handle this?  I see a bunch of stuff in a Google serach about 802.1q, less about .1p.  Sorry, I know Linux pretty well (I think I do at least), but I'm dumb when it comes to this stuff.  I've set up and run my own Linux NAT/router a long time ago, but that's when it was a simple cable modem with no vlan or QoS type stuff.
