Ports report 'closed' instead of 'stealth'
I just installed the RBE771/770 and ran Gibson Research's (grc.com) Shield's Up! 'port authority' scan. It reports that all ports are "closed", which means they are detectable by scans from the Inte...
Historically we've never see all ports marked for Stealth on Orbi systems. Mostly been always closed save some of apps or devices connecting thru may change to stealth.
We've brought this up to NG before. I did this years ago on the CBR50 back then.
Just not sure if NG intends to follow what GRC puts forth.
Will see if anything happens here.
That's simply not true. My Orbi RBR50, which I had for years and just replaced, ALWAYS showed all ports as Stealth.
And thats based of older FW code which doesn't have newer features like protection engine that seems to be now seen under the hood in newer Orbi models.
FW code has changed greatly since the Orbi AC series. Possible that NG maybe taking different development paths in FW and may not follow what we might expect to see from GRC Results.
Only NG engineering would know though.
Something to submit a support ticket about and let NG know and see if you get any feedback.
And for one of my Orbi BE Systems, here is results for it:
It's not a matter of how NG plays with GRC - the point is that the router is responding to unsolicited probes, making the network visible to the bad guys and a potential target. Although the risk is probably small, it would be zero if the router didn't respond at all to unsolicited probes (i.e if the ports were reported as stealthed in the GRC test), rendering the network invisible. I have submitted a support ticket to NG and I'm awaiting a reply.
PS - it's interesting that some of your ports are showing as stealth....
