I have noticed that after some unspecified amount of time, er605 stops port forwarding on wan1-wan3, I experience it for now mostly only wan3, wan1 and wan2 do not work either after a week or so, rebooting er605 resolves the issue on wan1 and wan2, but wan3 simply does not port forward even after reboot, have to reset and readapt it to get port forwarding to work again and in a day or two first wan3 stops port forwarding, then after unspecified amount of time, wan1 and wan2 stops port forwarding too and only wan works. I might have not noticed it with previous firmware. Controller is v5.3.1.

It seems that you are using all the 4 WAN ports at the same time.

How many port forwarding entries are configured on each WAN port?

How would the CPU/memory change before and after the port forwarding stops working?

May I know your network size? How many Omada devices are managed by the Controller?

There are only 20 rules, 6 of them are disabled, 14 active. All of them for all wan's. I changed yesterday all rules to not forward on wan3 and after some time wan2 and wan1 did not fail (maybe I have to wait longer, it is a change since maybe 9 hours ago). Then I deleted the rule, without reboot, added same rule again for all wan's and wan3 works for now.

Please keep monitoring and feel free to reply this thread if anything new came up.

If the issue can be reproduced steadily, I'd create a ticket and escalate the case for further follow up.
