In the file ~/.config/gnunet.conf I wrote this
ENABLE_UPNP = YES
The upnp command is available and upnp is enabled in the router
but still these 2 lines appear in the output
Jan 20 15:06:20-664904 nat-6787 WARNING upnpc failed to create port mapping
Jan 20 15:06:20-679750 nat-6787 WARNING upnpc failed to create port mapping
is anyone using upnp or are you all configuring the router by hand ?
