Gentoo upnp errors, failed to map the external wan port.

[frddbbbl]

Hi, I am trying to connect nicotine on my laptop running gentoo. I have just installed upnpc and receive the following errors.
UPnp exertion: Failed to map the external WAN port: AddPortMapping(15000, 2416, 127.0.0.1) failed with code 718 (ConflictInMappingEntry) Failed to automate the creation of upnp port mapping rule

I have soul seek on my MacBook which uses upnp and works fine. upnp is enabled on my router. any idea what I am doing wrong? can give more info if nessicary.

I am not a hundred percent sure, but that could arise when trying to map a port that's already bound to a different IP.

looking at my router gateway I don't see that port being used by another ip, it only has one port in use on 56822 on the Destination ip of a different device

I have tried a few different ports and all seem to return the same error( with a different port noted)

What is the output of these commands in a terminal?
upnpc -l
upnpc -e Nicotine+ -a 127.0.0.1 2416 15000 TCP
upnpc -e Nicotine+ -a 127.0.0.1 2416 2416 TCP
upnpc -e Nicotine+ -r 2416 15000 TCP

upnpc -l returns:

Seems like Nicotine+ uses the wrong local IP address.

Can you delete the existing entries? upnpc -N 0 15000 tcp
And try this command? upnpc -e Nicotine+ -a 192.168.1.109 2416 15000 TCP

This branch should fix the issue:
git clone -b upnplan https://github.com/mathiascode/nicotine-plus
