Home Hyper-V Networking Gotchas

I had not spotted that registry hack, months ago when I built my hyperV home setup.... therefore I have DHCP installed on the ISA Server virtual machine I always keep turned on, only bound to the "internal" NIC... the HyperV host has two NICs, but effectively communicated to the Internet THRU the virtualized ISA on the one that is "internal"... the other one is used for the ISA to go to the router, but the host does not use it.

Gotcha, good solution. My ISA Server is an optional web proxy, I just point Auto Detect clients at it through WPAD (I have an Xbox 360 on the network, so I don't want any port filtering to happen at the ISA box for that).

That said... I'm thinking I might put Forefront TMG on the host for general filtering and firewalling (or just WS2008 R2), and use the virtualized adapters to provide a dedicated "passthrough" router for the Xbox.

I also use WPAD, and I have an old XBox, and a Nintendo Wii, and a bunch of other devices that might need to go out unfiltered and/or unauthenticated: I just give them always the same IP Address thru RESERVATIONS in DHCP, and I let those IP out. All the rest in the dynamic IP range (=my kids and my wife's PCs) are allowed to go out for a few protocols, and have authenticated/filtered HTTP access (kids only have a whitelist of "allowed" sites... :-))

I am using virtual adapters for a sort of "DMZ", where I keep TEST machines that are in separate domains and don't have anything to do with "production" :-) ... so I can still send them out for WindowsUpdate, but they don't send crap (even just browser elections or any enumeration of stuff) out to my real internal net.

Yup - I found the ISA NAT implementation didn't mix with the 360 too well last time I tried it... I might give it another whirl with TMG.

I love being able to set up purely internal virtual networks where my virtual hosts congregate; I wonder if I could use that to perform a sneaky passthrough for the ISA host (connect the parent to a virtual network, and have ISA downstream of a virtual RRAS box (kinda what I did in the past, though more complicated))... best of both worlds... :)

I just bought a Q8300 as it was on the Intel list posted as having VT.. http://www.intel.com/products/processor_number/chart/core2quad.htm

It did not work, and it appears from the following that it does not have VT! http://ark.intel.com/cpu.aspx?groupId=39107

What a waste of money.. I only bought it to setup a hyper-v test machine!
