Not sure if this help either, but I run VMWare Player (5.0.0 on newer
64bit machine & 3.1.5 on 32bit machine) on my laptops and miredo (Teredo
tunnel) works w/o issue.
  Host(s): Ubuntu 12.04 and also Win7
   Guest(s): Ubuntu 12.04, Fedora 17, WinXP
Network: Wifi on the host
         Bridge from guest to host - host is running wifi only.

Sample from Ubuntu 12.04 guest:

Connection to shows all working fine. I can also connect
to other machines on my lan using ipv6.
