indeed Can you port forward with Ethernet?

Port-Forwarding works on IP addresses, so as long as you have valid IP address from the same router, you should be able to do whatever you need. Unless you have a crappy router who treats Ethernet and WiFi as separate networks, or you are connected to WiFi Guest network.

and Does port forwarding work with WiFi?

1 Answer. Port forwarding rules typically do not apply to connections originating from within your network.

Is it safe to open a port on your router?

Open ports aren’t dangerous by default, rather it’s what you do with the open ports at a system level, and what services and apps are exposed on those ports, that should prompt people to label them dangerous or not. The reason people call for closed ports because less open ports reduces your attack surface.

Why is port 8080 default?

“8080” was chosen since it is “two 80’s”, and also because it is above the restricted well known service port range (ports 1-1023, see below). Its use in a URL requires an explicit “default port override” to request a web browser to connect to port 8080 rather than the http default of port 80.

5. Step 4: On the Port Forwarding page enter in a name for your device like, “Camera”.

Is port forwarding safe?

Port Forwarding is not that risky because it relies on your network safety and the targeted ports that you are using. The whole process is actually safe as long as you have a security firewall or a VPN connection on your computer or network.

What is the purpose of port number?

Port number identifies a specific process to which an Internet or other network message is to be forwarded when it arrives at a server. Ports are identified for each protocol and It is considered as a communication endpoint. Ports are represented by 16-bit numbers.

Is it safe to open port 80?

Does port 445 need to be open?
