Customisation of the MacPorts download method

The virtual machine is using NAT.
I already checked with using a bridged network instead. With this setup curl download works again. But this workaround no longer works when bringing the VM up with vagrant.

Considering no one has told me how to change the MacPorts default download method, am I to assume there is no such option?

How have you figured the VM to connect to the network. Direct, or NAT ?

Does MacPorts work OK on the host machine directly ?

I have serveral OSX VMs running in a MacMini, previously running OSX
10.9 (now 10.10), and they worked just fine with MacPorts. I have them
connecting directly to my home network, so they appear as machines in
their own right on the network. This is with VMware fusion though, not
virtual box, which I am not familiar with, but I imagine it has similar
networking options... If you are currently using NAT, I would maybe see
if a direct connection helps ...
