 Updated on July 29, 2022:  

 

Add the Beta firmware for ER605 V2.

 

ER605_v2_2.0.2_Build 20220727 (Beta)

Note: Please be sure you have read the Beta Test Agreement before proceeding!

 

 

This Article Applies to:

 

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)

ER7206(UN)_v1_1.1.1_Build 20220117 (Beta)

Note: Please be sure you have read the Beta Test Agreement before proceeding!

 

For ER605 v1/v1.6, ER7206 v1/v1.6, please upgrade to official firmware 1.2.1 or above.

For ER605 v2/v2.6, please upgrade to official firmware 2.1.1 or above.

 

Thank you for your attention!

Works great.

 

For anyone flashing if it doesnt seem to work, go to firewall > attack defense and make sure "Block TCP Scan (Stealth FIN/Xmas/Null)" is enabled and "Block TCP Scan with RST" is disabled to achieve the desired results

 

EDIT:  The slow web interface bug (standalone mode) is back compared to the last couple of beta's  sad

Owner of: ER605 v1, ER605 v2, ER7206 v1, SG1024DE v4.2 and AX53 v1

@GRL 

 

Yeah...I had to revert back to 1.1.1 Build 20211012 Rel.53432.

I can't deal with that sluggish web interface that often won't load.

Thanks for your reply. I installed the firmware and all ports show stealth now.
