Is there any problem with Linksys port forwarding? You are not the only. Many users claim to have set the ports correctly, but for some reason, ports remain closed. The first thing to confirm if your Linksys port forwarding not working is that your device should have the static IP address. Check to see if your firewall settings are blocking traffic and that you are using the correct internal IP and port numbers. Reboot your router, too, with changes made; this sometimes makes the new settings take effect. Also, look for a firmware update along the way-it might clear away some more obscure bugs. If failure continues, maybe factory reset-it works sometimes as a last ditch. Fixing one of these typical issues will get Linksys port forwarding going again.
