Can anyone get the VPN to actually open a port?
Hello All, I have an ORBI RBE771. When I manage this device and click Enable VPN Service and select the default TUN and TAP mode ports (12973/12974) then go to this site to obtain my IP address: ht...
The default configuration for OpenVPN on Netgear orbi routers is to use the more efficient network alternative (UDP) rather than the more reliable, but less efficient TCP:
My impression is that most of the "is this port open?" resources send a TCP connection request to the IP address and look to see what happens:
- A response indicates the port is open
- A rejection indicates the port is closed
- No response at all indicates the port is "Stealth"
It is also absolutely essential that the Orbi router has a public IP address. This can be checked by comparing the IP address reported by the web resource against the value shown in the Orbi web interface Advanced Tab Home Page under Internet Port. If they are not the same IP address, then the Orbi router is "hidden" behind another router and cannot be reached.
