Some IT environments require the use of a proxy to connect to the Internet. Without this configuration VyOS updates could not be installed directly by using the :opcmd:`add system image` command (:ref:`update_vyos`).
.. cfgcmd:: set system proxy url <url> Set proxy for all connections initiated by VyOS, including HTTP, HTTPS, and FTP (anonymous ftp).
.. cfgcmd:: set system proxy port <port> Configure proxy port if it does not listen to the default port 80.
.. cfgcmd:: set system proxy username <username> Some proxys require/support the "basic" HTTP authentication scheme as per :rfc:`7617`, thus a username can be configured.
.. cfgcmd:: set system proxy password <password> Some proxys require/support the "basic" HTTP authentication scheme as per :rfc:`7617`, thus a password can be configured.
