Dyndns.class update

[obasi]

Added his function to get the WAN IP (Internet) regardless of setting.

              /*
	       * Private Function (added 07 July 08)
               * - Get the WAN IP
               */
		function _checkIP() {

			log_error("DynDns: _checkIP() starting.");

			$ip_ch = curl_init('http://checkip.dyndns.org');
			curl_setopt($ip_ch, CURLOPT_RETURNTRANSFER, 1);
			curl_setopt($ip_ch, CURLOPT_SSL_VERIFYPEER, FALSE);
			$ip_result_page = curl_exec($ip_ch);
			$ip_result_decoded = urldecode($ip_result_page);
			preg_match('=Current IP Address: (.*)=siU', $ip_result_decoded, $matches);
			$ip_address = trim($matches[1]);

			log_error("DynDns debug information: {$ip_address}");

			return $ip_address;
		}

Changed the $wan_ip lines in these two functions.

		function _detectChange() {

			log_error("DynDns: _detectChange() starting.");

			$currentTime = time();

			$wan_ip = $this->_checkIP();

		function _checkStatus($data) {
			log_error("DynDns: DynDns _checkStatus() starting.");
                        .
                        .
                        .
			if($successful_update == true) {
				/* Write WAN IP to cache file */
				$wan_ip = $this->_checkIP();

I hope this helps anyone habing trouble using the dyndns behind a NAT.
