Hi to all, sorry for my English but i'm italian...
Few days ago i tried to host a minecraft server out of nowhere but i encoutred this problem that is giving me nerves for days.
I've opened all the ports in the settings of the router and in the Windows Firewall, but the server still says this:
[23:22:06] [Server thread/INFO]: Starting Minecraft server on 194.39.145.253:25565
[23:22:06] [Server thread/INFO]: Using default channel type
[23:22:11] [Server thread/WARN]: **** FAILED TO BIND TO PORT!
[23:22:11] [Server thread/WARN]: The exception was: java.net.BindException: Cannot assign requested address: bind
[23:22:11] [Server thread/WARN]: Perhaps a server is already running on that port?
[23:22:11] [Server thread/INFO]: Stopping server
[23:22:11] [Server thread/INFO]: Saving worlds
[23:22:11] [Server thread/ERROR]: Exception stopping the server
java.lang.NullPointerException: null
As the server IP, i put my public address (194.39.145.253), if i put my local address (192.168.1.100), all works fine, but obviously the people that are outside of my local network can't join the server
That's a screenshot of the settings of my router, i know i gave you limited informations, but i'm here to resond. Thanks in advise for the help!
Because i'm a new user i can put only this screenshot, but if you need others just ask! 
Start the service not binding it to any specific socket.
If its scope is limited to localhost or local subnet by default, then use binding on the unspecified IPv4 address 0.0.0.0 and/or IPv6 address ::.
I did't understand, so i have to play it not in localhost, but online with other people...
And it fails to bind the port 25565, and in the site "canyouseeme.org" the port 25565 results closed also after open that in the settings
I'm not sure, but i think i get it, that's the result, is it correct?
But it still fails:

You can guide me to configure the port forwarding with my public Id? I searched and i found out i have to give my pc a static address, so i have done it.

Connect to OpenWrt with SSH and check:
uci show network; uci show firewall; \
ip address show; ip route show; ip rule show
https://openwrt.org/docs/guide-quick-start/sshadministration
It looks like your router has no public IP address.
You need to configure port forwarding on the upstream router with public IP.
