Hi,

NixOps provides two options that will allow accessing public and
private IP addresses. In your case you can use networking.privateIPv4.

>From the manual:

===========

networking.privateIPv4

IPv4 address of this machine within in the logical network. This
address can be used by other machines in the logical network to reach
this machine. However, it need not be visible to the outside (i.e.,
publicly routable).

Example: "10.1.2.3"

Declared by:

<nixops/options.nix>


networking.publicIPv4

Publicly routable IPv4 address of this machine.

Example: "198.51.100.123"

Declared by:

<nixops/options.nix>

===========

Cheers,
Rob
