Have you used a port check tool to see if your ports are actually open on the server?
You mention ports 2300-2350 UDP & TCP . those appear to be used by Heros 3 but you make no mention of the game nor all of the required ports.
Heroes Community - The ports H3 uses
You mention teamviewer3 but again don't confirm the ports you have configured
https://support.teamspeakusa.com/in...6/which-ports-does-the-teamspeak-3-server-use
You mention Minecraft which uses port 25565.
Please do the following:
post the results of a ipconfig /all for review
post the results of a tracert yahoo.com for review
list all games and ports associated with them you have configured in the router for review.
I did mention a game I was trying to run which is Arma 3 which requires at least ports 2302-2305 but it adds 12 to that for each instance of a game server running so I do that for redundancy.
