Hi, Christopher.

The VM's should be using the host computer's NIC's to access the LAN.

Can you access the web from the host computer?

Check if an environment variable is set on the host:

  printenv http_proxy

If it is, use the same setting on your VM's:

  export http_proxy=http://myproxy.mydomain

Where myproxy.mydomain is the setting of http_proxy on the host OS.

To do this permanently, you need to configure APT to use a proxy. This
is how I do it for my workstation:

  vim /etc/apt/apt.conf.d/01proxy
  ...
  Acquire::http::Proxy "http://proxy.abdn.ac.uk:8080";
  ...

HTH,

  Tony.
