<p class="infohelp">The router configuration options listed below are not available in the user interface, usually because they are rarely used or provide access to advanced settings that most users will not need.
This is not a comprehensive list.
Some settings will require a restart of the router to take effect.
Note that all settings are case sensitive.
You will need to edit your <code>router.config</code> file to add options, or, once you have added <code>routerconsole.advanced=true</code> to the router.config file, you may edit settings within the console on the <a href="/configadvanced">Advanced Configuration page</a>.</p>
<tr><td class="infowarn">Only set this to true if you know what you are doing!</td></tr>
<tr><td>When set to true, additional functionality will be enabled in the console and the user will be able to edit settings directly on the <a href="/configadvanced">Advanced Configuration page</a>.
Extra display options are provided in the <a href="/netdb">Network Database section</a>, including the <a href="/netdb?f=3">Sybil Analysis tool</a>, and there are additional configuration options on the <a href="/configclients">Clients Configuration page</a>.
This will also enable the installation of unsigned updates, manual configuration of the news URL, and the installation of plugins.
You may also wish to enable the "Advanced" sidebar section on the <a href="/configsidebar">Sidebar Configuration page</a>.</td></tr>
<tr><td>This setting allows the manual selection of the browser which I2P will launch on startup (if the console is <a href="/configservice#browseronstart">configured</a> to launch a browser on startup), overriding the OS default browser.</td></tr>
<tr><th>router.updateUnsignedURL={url}</th></tr>
<tr><td>This setting allows you to configure the update url for the unsigned update feature, if enabled.
The url should end with <code>/i2pupdate.zip</code>.
Note: do not install unsigned updates unless you trust the source of the update!</td></tr>
<tr><td>When set to true, if your router is serving as a floodfill for the network, your <a href="/configadvanced#ffconf">floodfill participation</a> will be hidden from other routers.</td></tr>
