| 23 | <p>If your port is still not open, even after you have enabled automatic port forwarding, here are some tips you can use which may get it working. |
|---|
| 24 | <div id="pagetitle"> |
|---|
| 25 | <h1>UPnP</h1> |
|---|
| 26 | </div> |
|---|
| 27 | <p>For UPnP compatible routers, make sure: |
|---|
| 28 | <ul> |
|---|
| 29 | <li>UPnP is enabled. Consult your router's documentation for instructions. If your router doesn't support UPnP, you will have to forward <a href="pfrouter.html">manually</a>.</li> |
|---|
| 30 | <li>DMZ mode is disabled.</li> |
|---|
| 31 | <li>The port has not already been forwarded manually. |
|---|
| 32 | </ul> |
|---|
| 33 | |
|---|
| 34 | <p>If you are still having problems, open the Message Log (in the Window menu) and post the debug output on the <a href="http://transmission.m0k.org/forum/viewforum.php?f=2">support forums</a>. |
|---|
| 35 | Make sure you pause your torrents first; then clear the log, and toggle "Automatically forward port". Post this output. |

| 40 | <p>If you have an Apple Airport, make sure NAT-PMP is enabled. |
|---|
| 41 | <div summary="To do this" id="taskbox"> |
|---|
| 42 | <p>To do this on Tiger/'Airport Admin Utility': |
|---|
| 43 | <ol> |
|---|
| 44 | <li>Open Airport Admin Utility</li> |
|---|
| 45 | <li>Select your base station and click "Configure".</li> |
|---|
| 46 | <li>In the "AirPort" tab, click "Base Station Options...".</li> |
|---|
| 47 | <li>In the "Ethernet Port Security" tab, check the "Enable NAT Port Mapping Protocol" checkbox.</li> |
|---|
| 48 | <li>Click "OK".</li> |
|---|
| 49 | <li>Click "Update". |

| 70 | <p>Another possible reason your port remains closed could be because your router is not the only device on the network which needs to be configured. |
|---|
| 71 | |
|---|
| 72 | <p>Make sure the OS X firewall is either disabled, or you have <a href="pffirewall.html">allowed Transmission's port</a>. |
|---|
| 73 | The firewall can cause the port to remain closed, even if it has been successfully mapped by the router. |
|---|
| 74 | |
|---|
| 75 | <p>If you have multiple routers in your home network, you must forward Transmission's port on all of them, otherwise it will continue to show up as closed. |
|---|
| 76 | Transmission can only automatically port map the router the computer is directly connected to. Any others in between this router and your modem will have to be <a href="pfrouter.html">forwarded manually</a>. |
