A minor addition: to use 'localhost' in beta 8 you may need to also run the internal debug command:

  pinata set native/port-forwarding true

In previous betas this setting was implied by "VPN compatibility" mode, but in beta 8 it was made an independent setting.

In beta 9 using localhost will be the default -- as avsm says we've been iterating on the network configuration trying to find the most compatible / least surprising defaults. Hopefully after beta 9 it will be stable on "localhost".
