Why can't people connect to my server?

[CrossfireTZ]

Two of my friends tried, and I tried from a different location, but nobody can connect to my server.

I've port forwarded port 25565 on TCP to my local IP (192.168.1.4) and I've let 25565 through my PC Firewall, but it doesn't let me connect.

My internet IP is 98.71.43.145.

Here's my server.properties:

#Minecraft server properties

generator-settings=

allow-nether=true

level-name=Tekkit

enable-query=false

Please help, if there's anything that's there to be fixed.

Check whatismyip.com to see if your ip is correct and make sure to try forwarding 25565 on UDP too.

The IP's still right, and I forwarded UDP as well, but my friends still can't connect.

try disabling the windows firewall and having them try a connection, also any other firewall you may have installed, then if you have multiple firewalls bring them back up one at a time till one stops the connection. if with the firewall down they are still unable to connect then double check your port forwarding in your router and make sure your pc is set to have a static ip. also if you have multiple network adapters you may want to check your priority settings for them.

25565 udp needs to be forwarded also.

Try using a port checker or port tester or something, see if 25565 is actually open.

If you name your router's brand and type number, that would probably help as well.

That IP looks like an internal IP, not an external one. Go to a website like the one posted above or ipchicken.com and use what it says your IP is.

Also, put the IP you get from the website of your choosing into your server.properties files under "server-ip".

That IP is an external IP. It's not Class C or any of the known private IP's, anyway.
