3To install NixOS behind a proxy, do the following before running
4`nixos-install`.
5
61. Update proxy configuration in `/mnt/etc/nixos/configuration.nix` to
7 keep the internet accessible after reboot.
8
9 ```nix
10 networking.proxy.default = "http://user:password@proxy:port/";
11 networking.proxy.noProxy = "127.0.0.1,localhost,internal.domain";
12 ```
13
141. Setup the proxy environment variables in the shell where you are
15 running `nixos-install`.
16
17 ```ShellSession
18 # proxy_url="http://user:password@proxy:port/"
19 # export http_proxy="$proxy_url"
20 # export HTTP_PROXY="$proxy_url"
21 # export https_proxy="$proxy_url"
22 # export HTTPS_PROXY="$proxy_url"
23 ```

26If you are switching networks with different proxy configurations, use
27the `specialisation` option in `configuration.nix` to switch proxies at
28runtime. Refer to [](#ch-options) for more information.
