# Configuring Proxy Settings

The cluster should have no access to the Internet and proxy settings `(http_proxy, https_proxy` and `no_proxy`) should not be set. However, if you need an Internet connection and you already specified a proxy server for http and https connection, then you must correctly configure `no_proxy`.

- No Proxy Definitions

- Proxy Settings Example

## No Proxy Definitions

If you have the `http_proxy` or `https_proxy` set, then the `no_proxy` definitions must contain at least the following values:

    no_proxy=localhost, 127.0.0.1, <all Master and Worker cluster node IP addresses>,<all Master and Worker cluster node FQDNs>,<HA virtual IP Address>,<FQDN for the HA Virtual IP address>

Incorrect configuration of proxy settings is a common installation issue. To verify that proxy settings are configured properly, on all master and worker nodes, run the following command and ensure the output corresponds to the recommendations.
`echo $http_proxy, $https_proxy, $no_proxy`

If the firewall is turned off, the install process generates a warning. To avoid this warning, set the OMT install parameter`--auto-configure-firewall` to true.

## Proxy Settings Example

Although the text here is displayed with line breaks due to page limitations, there should be no line breaks in your actual proxy settings.

    export http_proxy="http://web-proxy.http_example.net:8080"

    export https_proxy="https://web-proxy.http_example.net:8080"

    export no_proxy="localhost,127.0.0.1,node1.swinfra.net,10.94.235.231,node2.swinfra.net,10.94.235.232,node3.swinfra.net,10.94.235.233,node3.swinfra.net,10.94.235.233,node4.swinfra.net,10.94.235.234,node5.swinfra.net,10.94.235.235,node6.swinfra.net,10.94.235.236,ha.swinfra.net 10.94.235.200"
