Please copy paste the upper part of the log.

I think your IGD is 192.168.1.1:52869

Please try with the latest sources from https://github.com/miniupnp/miniupnp
and tell us which devices are connected to your network (brand/model of your router), device which has IP 192.168.1.103)

Hello,
I have installed openvpn service in my openwrt device (192.168.1.4) and manually configured port forwarding for port 1194 in my ISP's router (192.168.1.1). Everything is working fine.
Now I would like to go one step further and use upnp to do port forwarding configuration in the ISP router instead of doing it manually. I deleted the port forwarding entry (for port 1194) in the ISP router and installed, on my openwrt device, miniupnpd and luci-app-upnp. If my understanding is correct, miniupnpd will make my openwrt device an IGD (??). I also installed miniupnpc to make the device a upnp client.
I am using the default configuration for miniupnpd and added option log_output '1' to get logs.

I tried the following on openwrt device:

root@openwrt:/etc/# upnpc -a 192.168.1.4 1194 1194 udp


No IGD UPnP Device found on the network !
I was expecting that it will find IGD as 192.168.1.4 (itself)

When I check in the GUI of the ISP router I can see that an entry was created:
UPnP Control Point Table
IP Address MAC Address
192.168.1.4 xx:xx:xx:xx:xx:xx (I obfuscated the MAC address)

this entry disappered few minutes later.

Eventhough I have syslog-ng package installed, I checked the system logs but found nothing regarding upnp returned errors. I am blocked at this stage.
Any help is very much appreciated.

Thank you.

running upnpc on the same device where miniupnpd is running is not advised :
The default network interface will likely be directly connected to the internet, so upnpc could send UPNP discovery packets on the internet.

If you still want to do so, please use the -u or -m option to select the right "LAN" network interface for UPNP communication.
