RBR750 - Cannot port forward to PC connected to satellite router
Using latest firmware V4.6.5.14_2.0.54 Computer is running Windows 10 Setup: Spectrum Modem -> wired connection to Orbi base router -> wireless connection to Orbi satellite -> wired connection t...
Please define "static IP" (it can have multiple meanings)
- The IP was defined on the PC as static, and is within the Orbi IP subnet.
- The IP was "reserved" for the PC on the Orbi LAN setup page using the PC MAC address.
The IP was changed from DHCP to static on the PC. It doesn't show in the orbi device list in either configuration, however
With my batting average now.... zero, some random thoughts:
Static IP. I avoid static IP's partly because I tend to make typos when entering the parameters and do not double check my work. Everything has to be exactly correct: (a) being in the correct IP subnet, (b) having the correct subnet mask, (c) setting the gateway IP address, and even the DNS settings. Anything not perfect causes problems.
Connectivity. With the PC able to use the internet, it should be reachable from other devices on the LAN. i.e. Can it be pinged from a different device?
Firewall. The most typical issue with forwarding ports is that many computers (such as Windows) have different firewall rules for Private (the local LAN) and Public (everywhere else) access. If the device ever appears to the Orbi and port(s) are forwarded to it, firewall rules become critical. People frequently comment, "it works fine from home, but xxx web site claims the ports are not open," when the firewall is blocking Public access.
Satellite vs. Router. Would it be possible to (temporarily) connect the PC to the Orbi router rather than the satellite? I keep a couple of 50' ethernet cables around for just this purpose. The family could not stand ethernet cables running through the house, but every once in a while I have the house to myself and can string a cable to a device. Since this situation is "not supposed to happen", it would be useful to be able to state that the PC behaves normally when connected to the router but abnormally when connected to the satellite.
850 Firmware Issues. There is an absolute frenzy going on over in the AX community forum over the version 4.x firmware (as compared to the 3.x versions), especially with regard to satellites. I see plenty of frustration and even signs of desperation.
Is your Spectrum modem also a router or not in bridge mode? If you have Double Nat then often that causes port forwarding confusion. This post has some steps for us to diagnose your port forwarding problems: https://community.netgear.com/t5/Orbi-WiFi-6-AX-and-WiFi-6E-AXE/Community-FAQ-My-Orbi-port-forwarding-doesn-t-work/td-p/1984296
You should be able to port forward to your PC's internal IP address. Let us know what you find when following the steps to determine if you have Double NAT and what https://canyouseeme.org/ outputs (step #1). Also check if your PC is Windows that you have set the Orbi connection to Private Network (step #3).
