-
1
Log in to your router
Open your gateway IP (e.g.
192.168.1.1) and sign in with your admin credentials. -
2
Find the Port Forwarding section
Look in Advanced, NAT, or Virtual Servers — the label varies by brand.
-
3
Note the device's local IP
Go to the device you want to forward to and find its local IP address (e.g. 192.168.1.100). Assign it a static IP to prevent it changing.
-
4
Create the rule
Enter a name, the protocol (TCP, UDP, or both), the external port, and the internal IP and port of your device.
-
5
Save and test
Apply the rule, then test from outside your network using a port-checker tool or from mobile data.
Frequently Asked Questions
Does port forwarding work with a dynamic IP?
It will work until your public IP changes. Use a Dynamic DNS (DDNS) service to keep a stable hostname pointing to your router.
Is port forwarding a security risk?
Any open port is a potential entry point. Only forward ports you need and keep the target device's software up to date.
