I have a D-Link AC-3200 (DIR-890L), and Windows 10.
The problem I'm trying to solve is that I play a fairly old game (Warcraft 3 RoC), and I'm trying to host games. This problem is pasted all over the internet, but normally it's for windows xp, or 7.
Here's what I've done to allow connections through my windows firewall and router.
Allow app to communicate through Windows Firewall
Control Panel -> All Control Panel Items -> Windows Firewall -> Allowed Apps
I then checkbox
Warcraft III in both the public and private boxes and save.
I go to my router
Features -> Port Forwarding -> Add Rule
I add a rule that allows TCP and UDP port 6112 through to my Windows 10 IP address. It looks something like below
Status: Yes, Local IP: 192.168.0.2 (my computer IP), TCP Port: 6112, UDP Port: 6112, Always Enabled: Yes
To the best of my knowledge that should do it. I'm not sure how to troubleshoot this, but something is definitely still not letting the game through. I only have the one router, and no extra firewalls other than the windows 10 firewall.
