Is easy if you can connect to your OT is because u must been using Your computer ip to connect the one that always stars with 192.
U have blocked ports 7171 7172
I recomend u To use NO-ip,for example u get an ip called Server.no-ip.org
Server.no-ip.org will be in the config.lua where says:
-- Connection config
worldId = 0
ip = "server.no-ip.org"
Go to
No-IP - Dynamic DNS, Static DNS for Your Dynamic IPTo create ypur account, let me find you a tuto about how to register and that stuff.
