Go to https://www.whatismyip.com/ in your computer's web browser, then look at the number to the right of the "Your Local IP is:" heading. You'll need this in order to open your router's page:  Open Start {"smallUrl":"https:\/\/www.wikihow.com\/images\/0\/07\/Windowsstart.png","bigUrl":"\/images\/thumb\/0\/07\/Windowsstart.png\/30px-Windowsstart.png","smallWidth":460,"smallHeight":460,"bigWidth":"30","bigHeight":"30","licensing":"<div class=\"mw-parser-output\"><p>I edited this screenshot of a Windows icon.\n<\/p><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"http:\/\/en.wikipedia.org\/wiki\/Public_domain\">Public Domain<\/a><br>\n<\/p><\/div>"}  Open Settings {"smallUrl":"https:\/\/www.wikihow.com\/images\/d\/d0\/Windowssettings.png","bigUrl":"\/images\/thumb\/d\/d0\/Windowssettings.png\/31px-Windowssettings.png","smallWidth":460,"smallHeight":445,"bigWidth":"31","bigHeight":"30","licensing":"<div class=\"mw-parser-output\"><p>I edited this screenshot of a Windows icon.\n<\/p><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"http:\/\/en.wikipedia.org\/wiki\/Public_domain\">Public Domain<\/a><br>\n<\/p><\/div>"}  Click Network & Internet  Click View your network properties near the bottom of the page. Scroll down to the "Wi-Fi" section, then look at the number next to the "Default gateway" heading. Open a web browser, then enter the "Default gateway" address in your browser's address bar. If you're greeted with a login page, enter your router's username and password before proceeding. You may also be prompted to log in upon opening the Port Forwarding section. You may have to look for a Settings or Advanced Settings section first. Since all routers have slightly different pages, you may want to consult your router's manual for specific instructions. Enter your computer's local IP address in the "IP" or "Rule" text box. Click the "UDP" drop-down menu, then click TCP.  In some cases, you'll check the box next to "TCP" instead. If your rule already has "TCP" next to it, skip this step. Type 25565 into each of the "Port" text boxes. Scroll down and click Save or apply, then wait for the page to refresh. At this point, your Minecraft port should be forwarded, allowing others to join your server. Your router may reboot itself after you set this rule.
