I'm trying to setup a minecraft server:
server is on ubuntu comp, client on windows comp.

1) On my.public.ip.adress I can't play:
java.net.connectException: connection refused: no further information:80.80.80.80:25565

2) On 192.168.1.40(similar server's IP) it works, can play on LAN

---

So problem must be port forwarding:

3) tried the 25565 but also tried with another one.

4) on router i've set: 
NAT/virtualServers/add ----> 25565,25565,TCP/UDP,25565,25565,192.168.1.40
also 
NAT/Port Triggering ----> 25565,25565,TPC/UDP,25565,25565.

5) at canyouseeme.org it CAN see my service at 80.80.80.80:25565, it's visible.

6) at server's config file set: online mode:true/false both don't work

7) server's logs don't show any attempt of connection, problem must be on the router side.

halp! U\_U

EDIT: window's firewall desactivated. still don't work
