ER605(UN)_V1_1.1.1_Build 20210723 and earlier firmware
ER7206(UN)_V1_1.1.1_Build 20210723 and earlier firmware
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.
Welcome to download the Beta firmware below, and verify it does resolve your concern effectively.
ER605(UN)_v1_1.1.1_Build 20220117 (Beta)

@Fae I just recently got my ER605 and also found the newest iofficial firmware did not stealth all of my ports. Thank you for providing this beta release. GRC reports all 1055 ports are stealthed. Performing an external nmap scan against my public IP reports full stealth.Looking forward to it being included in the official release! For reference I am self hosting the Omada controller in a container using podman, works fantastically well and without issue! No problems upgrading via Omada controller. Cannot thank you enough fBor this.

@Fae - thanks - I can confirm that the new firmware has done the trick!
I note that the status page of the ER605 V2 now has "Confidential Only For Test" written on it; I guess this is just because it's beta.
It's working though, so thanks very much to you and the dev team!
