R7000 V1.0.11.136_10.2.120 port 520 is visible and closed (not stealth)
Doing a port scan on the R7000 with the latest 2 version of the firmware shows that port 520 is closed but not stealth. Port 520 is "efs" extended file name server. This might be the internal USB R...
I was curious about this as well so I put my R7000 online with CM1200 modem.
I had v.134 loaded then also loaded v.136 and factory reset the router and setup from scratch.
Both report port 520 is Stealth'd:

Tested both on a wired WIndows 10x PC and a Mac Book Pro 2018
uPnP test also passing as well.
Test on wired PC everything else disconnected.
Router setting everything disabled no RIP, no port forward, no Readyshare, no USB, no uPnP, No dynamic IP, no VPN, setup as router, no Static routes, no IPv6, no Bridge.
Total basic striped down.
After I found the port was not stealth, I tried most settings. I even was resetting the router. Still not stealth.
Please post a screen capture of this result.
Well I cant se what use a screenshot can do. But anyway, here it is.
Found I was having Rip v1 enabled. Tried to disable RIP. But doing that exposed port 68 also as closed.
And also port 520 was still visible. And as I sometimes uses a Wi-Fi extender I will leave RIP enabled.
Reenabling it, makes port 68 stealth again.
I was wandering if it is possible to find some of the old firmware versions.
Last two firmware updates has this 'BUG'. But I know for sure, that the version prior to this, was 100% stealth.
Cant remember the version number.I was curious about this as well so I put my R7000 online with CM1200 modem.
