Take careful note of the following issues when using standard, common http(s)/SOCKS4(a)/5 proxies -- anonymizers that only use http(s)/SOCKS4(a)/5 as an interface Like the Tor, or [[I2P]] software. are exempt.
* Most problems with these proxies are not caused by {{project_name_short}}.
* Connections to proxies are unencrypted and therefore should not be used to hide Tor use. This is because proxies are a type of tunnel-link which are not VPNs or SSH. Despite being unsuitable for hiding Tor due to the lack of encryption, in certain circumstances proxies might still be useful for users to circumvent censorship.
* If state-level censorship of the Tor network must be circumvented, then a better solution may be [[Bridges]] or other [[Lantern|alternative]] [[Anon_Connection_Wizard|circumvention]] [[Censorship_Circumvention_Tools|tools]]. Users in China are [https://web.archive.org/web/20171218203107/https://www.cs.uml.edu/~xinwenfu/paper/Bridge.pdf unlikely to circumvent government censorship] with vanilla bridges, as they are uniformly blocked. That said, Anon Connection Wizard configured with the meek-amazon or meek-azure pluggable transport was reported to bypass Chinese censorship in late 2017. Unfortunately the meek-amazon pluggable transport was [https://gitlab.torproject.org/legacy/trac/-/issues/26098 deprecated in 2018] after Amazon removed the domain fronting option.
* Be especially careful with http(s) proxies. Some of them send the [[Whonix_versus_Proxies#Summary|X-Forwarded-For]] header which discloses the IP address. http(s) proxies that do not send this header are sometimes called "elite" or "anonymous" proxies.
* When using X-Forwarded-For http(s) proxies, Tor entry guards and Tor [[Bridges|bridges]] can determine the IP address.
* The unencrypted nature of proxies makes them unsuitable to hide Tor from destination websites. For simple IP logging / IP detection they might work unless they’re http(s) proxies and send the X-Forwarded-For header.

= Proxy Configuration Prerequisites =
{{mbox
| type = notice
| image = [[File:Ambox_notice.png|40px|alt=Info]]
| text = '''Tip:''' In order to configure a proxy, three things must be known in advance:
# where the proxy is running;
# the IP and port of the proxy; and
# what type of proxy is being used.
}}
== Location of the Running Proxy ==
The location of the running proxy is variable and depends on the user's system. Refer to the following resources for examples:
* '''A)''' Proxy software might run on a remote computer, which is easier to set up.
* '''B)''' Proxy software (such as [[lantern|Lantern]]) create a proxy tunnel on the local computer.
** [[Qubes|{{q_project_name_long}}]] VM: [[lantern|Lantern]] as an example.
** [[Non-Qubes-Whonix|{{non_q_project_name_short}}]] VM: This is not yet fully documented, please [[contribute]].
*** The proxy software must run either:
**** '''B1)''' {{project_name_gateway_long}} under the Linux user account tunnel; or
**** '''B2)''' on the host {{Os}} (outside any {{VM}}); or
**** '''B3)''' in another VM.
*** All of this is [[Unsupported|undocumented]].

**** custom proxy software setup example.
== The Proxy IP and Port ==

| text = If the proxy IP address and port is known, this section can be skipped.
}}
* If custom proxy software will be run on {{project_name_gateway_short}}, then this configuration is also called localhost. Usually the proxy IP address is 127.0.0.1.
* Note: It is necessary to use the IP address instead of the hostname (proxy.example.com). If the proxy IP address is unknown, then in a terminal on the host {{Os}} (outside of any {{VM}}), run (Linux) nslookup proxy.example.com; replace proxy.example.com with the hostname of your actual proxy. Using the IP address instead of hostname might cause subtle fingerprinting issues -- see the footnote https://web.archive.org/web/20201214130728/https://github.com/Whonix/Whonix/issues/94 for more information.
== Type of Proxy in Use ==
It is necessary to know the proxy type from the following list:
* HTTPProxy
* HTTPSProxy
* Socks4Proxy
* Socks5Proxy
Also check whether the proxy requires a username and/or password beforehand.

User → proxy → Tor → Internet
Tor natively supports proxy settings and only requires editing of the torrc file.
== Option 1: Use {{Code2|Anon Connection Wizard}} ==
/usr/local/etc/torrc.d/50_user.conf.
Depending on your proxy configuration, add the necessary settings to the /usr/local/etc/torrc.d/50_user.conf file. For more information on these settings, refer to the [https://2019.www.torproject.org/docs/tor-manual.html.en Tor manual] ([http://jqyzxhjk6psc6ul5jnfwloamhtyh7si74b4743k2qgpskwwxrzhsxmad.onion/docs/tor-manual.html.en .onion]) and read the [https://gitlab.torproject.org/legacy/trac/-/wikis/doc/TorFAQ#my-internet-connection-requires-an-http-or-socks-proxy FAQ].
