Port Forwarding Issue
I recently got the Orbi AXE11000 (RBKE963B) Mesh system for my house my set up is as follows:
Modem: S33 SURFboard
Router: Orbi AXE11000 (RBKE963B) Mesh system
(1 satellite c...
What is the brand and model# of this PC?
Is the PC ethernet or wireless connected to the RBS?
What is the brand and model# of the ethernet or wifi adapter in this PC?
Be sure any ethernet or wireless adapter cards have there drivers updated.
For ethernet connections be sure your using too quality LAN cable. CAT6 is recommended for the 1Gb LAN ports. CAT6A STP is recommended for the 2.5Gb ports.
What is the brand and model# of this PC?
- it is a personally built PC. The mother board is (ASUS ROG Strix Z690-G Gaming Wifi 6E part number- 90MB19G0-M0AAY0)
Is the PC ethernet or wireless connected to the RBS?
- PC is connected via ethernet to the RBS
What is the brand and model# of the ethernet or wifi adapter in this PC?
- The lan is a built in Intel I225/I226 adapter on the mobo
Be sure any ethernet or wireless adapter cards have there drivers updated.
- OS for the computer is unraid. The ethernet drivers are updated
For ethernet connections be sure your using too quality LAN cable. CAT6 is recommended for the 1Gb LAN ports. CAT6A STP is recommended for the 2.5Gb ports.
- Using CAT7 cables for the connection
Prior to the switch to the ORBI Mesh routers I was using the Xfinity ISP provided router and the device showed up in the attached devices
I have never seen documentation explaining how the system detects a device connected to a specific Ethernet port. My suspicion is that the router uses Address Resolution Protocol (ARP) to determine the MAC address of a specific IP address and then pulls the connection information from internal MAC tables.
Is there a method you can use to determine if this computer is responding to ARP requests? I would connect a laptop computer to another Ethernet port on the same Orbi unit that the computer is connected to and attempt to ping the computer by IP address. What should happen is:
- The laptop recognizes that the target is on the same LAN as the laptop (because of the subnet mask)
- The laptop looks in its ARP table to find the MAC address to send ICMP requests (ping) to.
- Oops, this IP is not in the ARP table, so use ARP to discover the MAC address.
- The computer responds to ARP with "That IP belongs to ME at this MAC address"
- The computer sends ICMP messages to that MAC address.
By being connected to the same Ethernet module, the only part of this traffic that leaves the module is the original ARP request (because it is a broadcast packet) and the ARP response (also a broadcast) The ICMP messages will go from one port in the module to the other port in the module. The responses also will not leave the Ethernet module.
So \I want to clarify. I am not trying to verify the device is connected to a specific port on the Satellite. I am trying to port forward to the computer.
The computer is not showing up on the attached devices list no matter which port it is connected to, but IS getting an internet signal. I am able to connect to the internet and the device picks up that there is a 2500 Mbps connection. I am also able to ping the device on the internal network using the static IP. There is another device hardwired to the same satellite and it shows up on the attached devices list. Also I have connected the computer to the router itself and it still doesnt show up.
The router is not port forwarding to the computer currently. The computer has a static IP and in the port forwarding table i identified the static IP that i want it to forward the data to. Not sure what I can do to verifiy if the ports are actually being forwarded to the device.
