I installed linuxigd-1.0 with libupnp-1.3.1 in my PC.

I started the daemon by giving

upnpd -f eth1 eth0

I am getting error in registering root device with descdocURL

upnpd[22186]: UPnP SDK Successfully Initialized.
upnpd[22186]: Succesfully set the Web Server Root Directory.
upnpd[22186]: Error registering the root device with descDocUrl:  http://192.168.3.31:49152/gatedesc.xml
upnpd[22186]:   UpnpRegisterRootDevice returned -108

Can anyone help me in clearing this error

Thanks
