Edit on April 28, 2022:  


Before you upgrade the 1.2.0 firmware above, please take a few seconds to read the note below:


If you have set a Source/Destination Network with "!" to create the ACL rules, after you upgrade to the 1.2.0 firmware, the Source/Destination Network will also include the gateway itself, which may result in an issue that clients are unable to obtain IP addresses from the DHCP(the gateway).


This has been confirmed to be a bug and will be fixed in the next firmware update. As a temporary solution, you may adjust your ACL rules without using "!" for the Source/Destination Network, or stay in the current firmware version and wait for the next firmware update patiently (I don't have ETA for it).


Sorry for any inconvenience caused!
