Why?]]></title><description><![CDATA[<p dir="auto">Hi everyone!  :)</p>
<p dir="auto">I have a issue that drives me crazy for 2 days !! My WIFI devices can't see each other !  ???</p>
<p dir="auto">But let's start with the configuration first:</p>
<p dir="auto">I am running pfsense <strong>2.1.5</strong> on a Alix 2D2 Wifi (3 physical interfaces, 2 Ethernet, 1 WIFI).</p>
<p dir="auto"><strong>Interfaces:</strong></p>
<p dir="auto"><strong>WAN</strong> is connected to a cable modem,<br />
<strong>LAN</strong> is an Regular Lan with a DHCP,<br />
<strong>WIFI</strong> just enabled with no IPv4 or IPv6 configuration.</p>
<p dir="auto"><strong>LAN</strong> and <strong>WIFI</strong> are bridged together (bridge named: <strong>BRIDGE_0</strong>)</p>
<p dir="auto"><strong>BLAN</strong> is an interface with <strong>BRIDGE_0</strong> affected to it.</p>
<p dir="auto"><strong>net.link.bridge.pfil_member</strong> is set to 0,<br />
<strong>net.link.bridge.pfil_bridge</strong> is set to 1.    I don't understand why, but I saw on the forum that it has to be like that.  ???</p>
<p dir="auto"><strong>Firewall:</strong></p>
<p dir="auto">no security at all !!  everything is opened to everything.</p>
<p dir="auto"><strong>What's working:</strong></p>
<p dir="auto">All devices (cable or WIFI) can get an IP from the DHCP,  :D<br />
All devices can reach the Internet,  :D<br />
All devices on the LAN (cabled) can see all the other devices (cable or WIFI).  :D</p>
<p dir="auto"><em><strong>BUT</strong></em></p>
<p dir="auto">No WIFI devices CANNOT see or ping any other WIFI devices !!  :(<br />
All WIFI devices CAN see all cabled devices.  :o</p>
<p dir="auto">For instance, my laptop (WIFI) can't see my wifi printer, but it can see my Dlink NAS (Cabled).  :-\</p>
<p dir="auto">I don't know what to do !</p>
<p dir="auto">Is anyone has an idea on that ?  :)</p>
<p dir="auto">Thankin advance for the brainstorming !</p>

<p dir="auto">you have to select :</p>
<ul>
<li>"Allow packets to pass between wireless clients directly when operating as an access point"<br />
in menu : interface &gt; (WIFI interface) &gt; "Network-Specific Wireless Configuration"</li>
</ul>
<p dir="auto">(pfsense 2.3.3)</p>
<p dir="auto">Idf not selected, it works in isolated mode.</p>

All traffic has to go through it, and it decides if it's going to forward that traffic to another wireless client, which typically is not something you want in an isolated AP.</p>
