You can simplify the process of setting up port forwarding if your router supports automatic port mapping protocols such as NAT-PMP or <acronym po4a-id=0>UPnP</acronym>. For more information, see <a po4a-id=1>What is NAT-PMP / UPnP?</a>.

All broadband <acronym po4a-id=0>SOHO</acronym> routers that manufactured in the recent years should support at least UPnP and it should be enabled by default (this may not always true for older models). In any case its best to consult the documentation of the device about what port mapping protocol does the router support and how to enable it.

Currently, DC++ includes support for both UPnP and NAT-PMP. If automatic port mapping is enabled in the connectivity configuration DC++ will try to map the ports with all the available mapper interfaces until a successful attempt. To enable automatic port mapping

Select the <b>Active mode (let DC++ configure my router with NAT-PMP / UPnP)</b> radio button. Leave the fields in the "External / WAN IP" box blank.

Test active mode by joining several hubs and doing a search for a common term. You should get results back. If not, then open the <a po4a-id=0>System Log</a> window and check the last log messages about the port mapping attempts and possible errors.

Here are some tips if you can't make the automatic port mapping work and unable to figure out what's the problem:

Make absolutely sure you have properly configured your <a po4a-id=0>security software to unblock DC++</a>

When automatic port mapping is selected DC++ tries all the included mapping interfaces one by one, until a successful result. The default order of the implementations is pre-determined but you can force what mapper DC++ should try first. It's possible that DC++ gets a successful signal from a certain mapping interface (you see successful port mapping results in the <a po4a-id=0>System Log</a> window) but searches and downloads still don't work as the port mapping operation is actually failed. In this case you can <a po4a-id=1>select another mapping interface to try first</a> in a hope of a better result.

Try to <a po4a-id=0>set your external IP manually</a> (see above how to determine it) especially if you see 'Port mapping: Failed to get external IP' message in the <a po4a-id=1> System Log</a> window or wrong IP addess shown if you use the /conn chat command. Don't forget to <a po4a-id=2>disallow the automatic IP override</a> in these cases.
