OpenWRT supports all the IPv6 stuff you're asking for in the latest release. Buy any router supported by that version of OpenWRT. Personally I use an alix 2d13, works great.
I've done benchmarks previously. With OpenWRT it'll do around 50k packets/sec at 64 byte frame sizes. It will do line rate at higher (100meg) at larger frame sizes.
I've got several alix 2d13 boards. Rock solid. They run OpenWRT extremely well. A little light on memory for anything else. pfSense will run but the OS timers are not fast enough to do decent QoS on it. On Linux it smokes.
This is not an "Apple" problem. This is a Bonjour protocol implementation detail. It's for local subnets, it's broadcast based, and uses multicast. You should look into wide-area discovery, this link, http://www.dns-sd.org , has some information on it.
Or...you know...you could just have one...
Have Time Warner business class at home through work at 50/5. Always been very impressed with their customer and technical support. Not sure I'd pay those prices for it though, wow.
Of course it doesn't. If you change it to 8.8.8.8 or 4.2.2.2 then you aren't using OpenDNS any longer. You can either:
1. stop users from changing the DNS servers on the PC
or
2. block requests to unknown DNS servers from getting out to the internet. i don't know if you router can do that.
Too bad Creative's drivers are absolutely shitty and always have been. Since the beginning of time. I didn't think people still bought stand alone sound cards.
Those look like management settings to me. So, a "dumb switch" like this could use DNS to:
1. check for software updates
2. use for NTP server sync
3. any number of other management related tasks
It wouldn't use any DNS to do anything regarding actually switching traffic.
Seems like asking for trouble to me. Do those extra PROset tabs add a bunch of bloat? I've been using the entire package for eons now and have never had any problems with them.
