Add new nat rule with PEAR2 PHP

Tue Oct 22, 2013 10:27 am

Hi guys, im scripting a new code to add nat rules on mikrotik, and i need some help :S

This is the code:

php code

<?php 

 //Listas desplegables
 
echo "</br>";

//Peticion a la API
$addRequest = $client->sendSync(new RouterOS\Request('/ip/firewall/nat/add'));

echo "<table align='center' border=2 bordercolor='000000'><form action='' method='POST'>";
echo "<tr bgcolor='#D8D8D8'><td align=left size=3>Accion</td><td align=left size=3>Direccion Origen</td><td size=3>Direccion Destino</td>
						    <td size=3>Protocolo</td><td size=3>Puerto Origen</td><td size=3>Puerto Salida</td><td align=left size=3>Agregar</td></tr>";




echo "<tr>
<td>
		<input type='radio' value='srcnat' name='chain'>Src</input>
		<input type='radio' value='dstnat' name='chain'>Dst</input></td>
		
		
		<td>
		<select name='src-address'>
				<option value='192.168.2.2'>192.168.2.2</option>
				<option value='192.168.2.3'>192.168.2.3</option>
				<option value='192.168.2.4'>192.168.2.4</option>
	            <option value='192.168.2.5'>192.168.2.5</option>
																
		</select></td>";
		
echo "<td><select name='to-addresses'>
				<option value='65.23.23.1'>65.23.23.1</option>
				<option value='65.23.23.2'>65.23.23.2</option>				
				<option value='65.23.23.3'>65.23.23.3</option>
				<option value='65.23.23.4'>65.23.23.4</option>		
		</select></td>";
		
echo "<td><select name='protocol'>
				<option value='tcp'>tcp</option>
				<option value='udp'>udp</option>				
				<option value='gre'>gre</option>
				<option value='icmp'>icmp</option></td>";		
 

echo "<td><input type='number' min='1' max='65535' name='src-port' value='' /></td>";     
echo "<td><input type='number' min='1' max='65535' name='to-ports' value='' /></td>";
 
echo "<td><button type='submit' name='add' value='add'>Agregar</button></td></tr>";
 
echo "</form></table>";
I need complete this code, but i dont know how..

P.D: I have this code too:
Code: Select all
$addRequest = new RouterOS\Request('/ip/firewall/nat/add');
$addRequest->setArgument('chain', 'dstnat');
$addRequest->setArgument ('protocol', 'tcp');
$addRequest->setArgument('action', 'dst-nat');
$addRequest->setArgument('to-addresses', '192.168.2.3');
$addRequest->setArgument ('to-ports', '4562');
But now, how i can convert this in a form? :S

Thanks :)

This line alone
Code: Select all
$addRequest = $client->sendSync(new RouterOS\Request('/ip/firewall/nat/add')); 
doesn't really add anything, since add requests need to actually contain the properties to be added.

You need to inspect the $_POST array, and convert it to the arguments.

Alternatively, you can just use the Util class, to which you can pass the $_POST array, MINUS anything that isn't property/value pairs to be added. E.g.

php code

<?php 

 //Listas desplegables
 
echo "</br>";

$util = new RouterOS\Util($client);
$util->changeMenu('/ip/firewall/nat');

//Peticion a la API
if (isset($_POST['add'])) {
    unset($_POST['add']);
    if ('' == $util->add($_POST)) {
        echo '<div class="error">Failed to add rule</div>';
    }
}

echo "<table align='center' border=2 bordercolor='000000'><form action='' method='POST'>";
echo "<tr bgcolor='#D8D8D8'><td align=left size=3>Accion</td><td align=left size=3>Direccion Origen</td><td size=3>Direccion Destino</td>
						    <td size=3>Protocolo</td><td size=3>Puerto Origen</td><td size=3>Puerto Salida</td><td align=left size=3>Agregar</td></tr>";




echo "<tr>
<td>
		<input type='radio' value='srcnat' name='chain'>Src</input>
		<input type='radio' value='dstnat' name='chain'>Dst</input></td>
		
		
		<td>
		<select name='src-address'>
				<option value='192.168.2.2'>192.168.2.2</option>
				<option value='192.168.2.3'>192.168.2.3</option>
				<option value='192.168.2.4'>192.168.2.4</option>
	            <option value='192.168.2.5'>192.168.2.5</option>
																
		</select></td>";
		
echo "<td><select name='to-addresses'>
				<option value='65.23.23.1'>65.23.23.1</option>
				<option value='65.23.23.2'>65.23.23.2</option>				
				<option value='65.23.23.3'>65.23.23.3</option>
				<option value='65.23.23.4'>65.23.23.4</option>		
		</select></td>";
		
echo "<td><select name='protocol'>
				<option value='tcp'>tcp</option>
				<option value='udp'>udp</option>				
				<option value='gre'>gre</option>
				<option value='icmp'>icmp</option></td>";		
 

echo "<td><input type='number' min='1' max='65535' name='src-port' value='' /></td>";     
echo "<td><input type='number' min='1' max='65535' name='to-ports' value='' /></td>";
 
echo "<td><button type='submit' name='add' value='add'>Agregar</button></td></tr>";
 
echo "</form></table>";
(Though keep in mind that with that approach, you don't get the exact error messages from RouterOS - you only know if adding failed or not, but not why)

I update the code, and its working, but i have another problem.
In radio buttons, when i choose src(chain srcnat), the action should be src-nat, and when i choose dst(chain dstnat), the action should be dst-nat
When i create a nat rule, it creates with action accept :S

Well then, simply express what you just said in code, right before you do the adding, i.e.
Code: Select all
//Peticion a la API
if (isset($_POST['add'])) {
    unset($_POST['add']);

    if (isset($_POST['chain'])) {
        if ('srcnat' === $_POST['chain']) {
            $_POST['action'] = 'src-nat';
        } elseif ('dstnat' === $_POST['chain']) {
            $_POST['action'] = 'dst-nat';
        }
    }
 
    if ('' == $util->add($_POST)) {
        echo '<div class="error">Failed to add rule</div>';
    }
}

        //Limit the action only to known ones, for security's sake
        if (in_array($act, array('set', 'remove'))) {
            $actionRequest = new RouterOS\Request("/ip/firewall/nat/{$act}");
            $actionRequest->setArgument('numbers', $itemID);
            if ('set' === $act) {
                foreach ($_POST[$itemID] as $name => $value) {
                    $actionRequest->setArgument($name, $value);

echo "<td><button type='submit' name='add' value='add'>Agregar</button></td></tr>";
  
echo "</table></form>";

?>
and the tables is something like that:

http://gyazo.com/5a871e913478c54f35b1435208b9e161

I need add nat rules without values too, without protocol, src and dst ports :S
The first table, with nat rules print, works very well, thanks to u too, but the new table to add new rules no :S

Re: Add new nat rule with PEAR2 PHP

Tue Oct 22, 2013 4:16 pm

Wait... you're writing both forms on a single PHP page?

That complicates things a little bit, as you need to unambigiously select one action to do upon submitting, since both codes would be executed.

You could perhaps rename the "add" button to "act" and have its value be "add[]". After that, combining the two processings is a piece of cake:

php code

<?php
use PEAR2\Net\RouterOS;
// require_once 'pear2\src\PEAR2\Autoload.php';
require_once 'PEAR2_Net_RouterOS-1.0.0b4.phar';
 
$client = new RouterOS\Client('192.168.150.161', 'admin', 'admin');
 
if (isset($_POST['act'])) {
    foreach ($_POST['act'] as $act => $itemID) {
        //Limit the action only to known ones, for security's sake
        if (in_array($act, array('set', 'remove', 'add'))) {
            $actionRequest = new RouterOS\Request("/ip/firewall/nat/{$act}");

            if ('add' !== $act) {
                $actionRequest->setArgument('numbers', $itemID);
            }

            if ('set' === $act || 'add' === $act) {
                if (isset($_POST[$itemID]['chain'])) {
                    if ('srcnat' === $_POST[$itemID]['chain']) {
                        $_POST[$itemID]['action'] = 'src-nat';
                    } elseif ('dstnat' === $_POST[$itemID]['chain']) {
                        $_POST[$itemID]['action'] = 'dst-nat';
                    }
                }

                foreach ($_POST[$itemID] as $name => $value) {
                    $actionRequest->setArgument($name, $value);
                }
            }

            $responses = $client->sendSync($actionRequest);
            $errors = $responses->getAllOfType(RouterOS\Response::TYPE_ERROR);
            if (0 === count($errors)) {
                echo "<div>'{$act}' OK!</div>";
            } else {
                echo '<div><ul>';
                foreach ($errors as $error) {
                    echo '<li>' . $error('message') . '</li>';
                }
                echo '</ul></div>';
            }
        }
    }

Apparently, an empty key name is not allowed... try the above now (where I've added a "*" in front of all fields on adding; I've also corrected the form itself - it should start before the table, and I've made the add form separate to avoid sending everything else when adding).

It adds the rule with 'accept' action, and when i refresh the page, it adds again the same rule..

Opps. I missed altering the "chain" pre-processing bit...

I've fixed it above.

For the duplicate adding issue, replace
Code: Select all
            if (0 === count($errors)) {
                echo "<div>'{$act}' OK!</div>"; 
with
Code: Select all
            if (0 === count($errors)) {
                header('Location: http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
                return; 
The redirect will force the browser to go back to the same page, but without any $_POST data following it. We do this only on success, since you may otherwise try to retry a previously failed request by refreshing the page.

An for the adding without empty values issue, replace
Code: Select all
                foreach ($_POST[$itemID] as $name => $value) {
                    $actionRequest->setArgument($name, $value);
                } 
with
Code: Select all
                foreach ($_POST[$itemID] as $name => $value) {
                    if ('' != $value) {
                        $actionRequest->setArgument($name, $value);
                    }
                }
