EndPoint Manager and NAT

I implented a hack, that I thought might benefit others.

  1. I added an item to template_data.xml:
        <item>
            <!-- Image Name -->
            <variable>$external_ip</variable>
            <default_value></default_value>
            <description>External IP Address</description>
            <type>input</type>
        </item>

  1. I created two clones, one for local phones and one for remote phones. In the clone for the remote phone, I put the external IP address for the PBX, in the clone for the local phones, I left it blank.

  2. I created a function in base.php called “parse_if” (which is just a slightly modified variant of “parse_loops”):

    /**
     * Parse data between {if_*}{/if_*}
     * @param string $line_total Total Number of Lines on the specific Phone
     * @param string $file_contents Full Contents of the configuration file
     * @param boolean $keep_unknown Keep Unknown variables as {$variable} instead of erasing them (blanking the space), can be used to parse these variables later
     * @param integer $specific_line The specific line number to manipulate. If no line number set then assume All Lines
     * @return string Full Contents of the configuration file (After Parsing)
     * @example {if_external_ip}{/if_external_ip}
     * @author Andrew Nagy
     */
    function parse_if($line_total, $file_contents, $keep_unknown=FALSE, $specific_line='ALL') {
        //Find line looping data betwen {line_loop}{/line_loop}
        $pattern = "/{if_(.*?)}(.*?){\/if_(.*?)}/si";
        while (preg_match($pattern, $file_contents, $matches)) {
            if(isset($this->options[$matches[3]]) and $this->options[$matches[3]] != "") {
                $parsed = "";
                $parsed .= $this->parse_config_values($matches[2], FALSE, "GLOBAL");
                $file_contents = preg_replace($pattern, $parsed, $file_contents, 1);
            } else {
                $file_contents = preg_replace($pattern, "", $file_contents, 1);
            }
        }
        return($file_contents);
    }
  1. Added call to “parse_if” under the call for “parse_loops”:
$file_contents = $this->parse_if($line_total,$file_contents, $keep_unknown = FALSE, $specific_line);
  1. Now, in my template I can have logic like this:
{if_external_ip}
#
# NAT
#
nat_enable: "1"
nat_address: "{$external_ip}"
nat_received_processing: 1
proxy1_address: "{$external_ip}"
proxy2_address: "{$external_ip}"
{/if_external_ip}
