<!--h3>Request socket permissions change</h3>

<p>You need to request socket permissions before you are able to open any network connections.

Please use the separate form at the bottom of this page for that. There is no need to wait until a request for socket permissions has been granted before starting to request firewall rules.</p>

<p>Keep in mind that, if your request is granted, it will never apply to existing log-in sessions. Close them and re-connect to take advantage of your new privileges.</p>

<h3>Request a new firewall rule</h3>

<p><b>This form isn't needed yet to allow you to use any port.  However, if you request a rule here, you can be sure it will be added when we first implement firewalls on our new servers.  Otherwise, your custom services may stop working.</b></p>

<p>You can find a description of rule formats <a href="http://wiki.hcoop.net/wiki/FirewallRules">on our wiki</a>. Enter here the rule you want, without the initial <tt>user</tt> portion.</p>

<p>Please note that <b>your firewall rule will be useless</b> if you don't first request the corresponding socket privileges at the top of this page. Also, common ports like 80 (HTTP) are open to everyone with socket permissions. Verify that you can't access a port after socket permissions have been granted before requesting a special rule here.</p>

<p>We very rarely grant requests for Client rules that don't include remote host whitelists. For example, important security concerns make it a bad idea for us to give anybody blanket IRC permissions. Instead, request specific servers. We will refuse such requests that include networks that are popularly considered fronts for illegal activity.</p>
