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 currently hooked up)
Firmware on router: 7.2.6.21
I have a computer connected to the satellite. The computer does not show up in the attached devices list. Ive had the computer set up with both dynamic and static IP addresses. It never shows up on the attached device list. The computer is able to connect to the internet. Ive connected the computer to different ports on the satellite, and different ports on the computer. It never shows up, but other devices hardwired to the satellite show up.
I am trying to forward two ports to the computer but it is not working. I am not sure what i can do to fix this issue. I have the ports forwarded to the static IP the computer currently has but it is not working and not sure what i can do to fix this

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.

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.
