# 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"
|
||
|
|
```
|
||
|
|
|
||
|
|

|
||
|
|
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.
