**Autor:** K.Heermann (flip-flop) http://planmatrix.de \\
**CMS version:** >= 1.4 \\ 
**Version:** V1.0 \\


**Tag** (in guestbook template): **<!--BAN_IP_START////-->** xxx.yyy.zzz.uuu xxx.yyy.zzz.* xxx.yyy.*.* **<!--BAN_IP_END////-->** \\

  * The last two places of the IP can be masked by the substitute symbol * 
  * Siehe zu IP auch [[http://en.wikipedia.org/wiki/IP_address|IP-address]]
  * Decollator of the IPs is a blank or a line-feed.

Example: <code>
<!--BAN_IP_START//-->
192.168.0.0 
92.241.154.* 
125.116.*.* 
91.191.*.* 
<!--BAN_IP_END//-->
</code>

**file name:** cnt18.article.inc.php 

**location:**   include/inc_front/content/  



Enhancement of the file include/inc_front/content/cnt18.article.inc.php for instance starting from line 330 directly forwards
<code php>
	// Captcha check
	if(empty($guestbook['captcha'])) { ........
</code>

<code php |h Banned IP |h >
	// Banned IP ================= +kh 24.10.09
	if( !empty($guestbook['ban_ip']) ) {
		
		$_ip      = getRemoteIP();

		$_ip01    = implode ('.',$_ipex);
		$_ipex[2] = '*';                      // 123.456.*.*
		$_ip02    = implode ('.',$_ipex);
		
		
		if ( strpos($guestbook['ban_ip'], $_ip01) OR // xxx.yyy.zzz.*
			 strpos($guestbook['ban_ip'], $_ip02) OR // xxx.yyy.*.*
			 strpos($guestbook['ban_ip'], $_ip) ) 
		{
			$guestbook['flooding']	= 1;
			$guestbook['readform']	= 1;
//		$guestbook['spamalert']	= '<div class="spamFormAlert">Your IP '.getRemoteIP().' is not allowed to send form (Blacklist)!</div>';
			$guestbook['spamalert']	= '<div class="spamFormAlert"><br /><hr><strong>Sorry, your are not allowed to send form!</strong><hr><br /></div>';
		}
	}

==== Template ====


In template now the exclusion of individual IPs or IP ranges is also possible:

E.g.:
<code>
<!--BAN_IP_START//-->
192.168.0.0 
92.241.*.* 
125.116.15.* 
91.191.*.* 
<!--BAN_IP_END//-->
</code>

<note important>
Be carefull by using a placeholder in the third position (xxx.yyy.##*##.*)!!! Often the two first places of the IP are used from several countries.
</note>
