+# Installing behind a proxy {#sec-installing-behind-proxy}
+
+To install NixOS behind a proxy, do the following before running
+`nixos-install`.
+
+1.  Update proxy configuration in `/mnt/etc/nixos/configuration.nix` to
+    keep the internet accessible after reboot.
+
+    ```nix
+    networking.proxy.default = "http://user:password@proxy:port/";
+    networking.proxy.noProxy = "127.0.0.1,localhost,internal.domain";
+    ```
+
+1.  Setup the proxy environment variables in the shell where you are
+    running `nixos-install`.
+
+    ```ShellSession
+    # proxy_url="http://user:password@proxy:port/"
+    # export http_proxy="$proxy_url"
+    # export HTTP_PROXY="$proxy_url"
+    # export https_proxy="$proxy_url"
+    # export HTTPS_PROXY="$proxy_url"
+    ```
+
+::: {.note}
+If you are switching networks with different proxy configurations, use
+the `specialisation` option in `configuration.nix` to switch proxies at
+runtime. Refer to [](#ch-options) for more information.
