Issue Description/Phenomenon:
From time to time, we received feedback that Omada Gateway cannot pass GRC Shields UP test, when using the ShieldsUp Website (grc dot com) to scan the ports, some ports are showing "Closed" instead of "Stealth" as expected.
Available Solutions:
The R&D team has made a Beta firmware to optimize the issue above. After upgrading to the Beta firmware, Omada Gateway will discard and not reply to inbound TCP SYN attempts to the WAN port, which should comply with Shield!up requirements.

Why is everyone not doing external port scanning? The easiest solution for this is to use GRC Shields Up. For those a little more enterprising use some external network and usually the easiest for most is a WiFi hotspot on your phone connected to a laptop and then run a simple nmap.
It is very sad that such a great product is still struggling with such a simple concept that for a router should not once ever have been an issue. Thanks but I'll stick with my UniFi, Ubiquiti and Microtik solutions.
