Port forwarding not working on all wan's after some unknown period of time

Hardware Version: V1
Firmware Version: 1.2.1

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?

  @Fae thanks for reply. It is not big network, around 50 devices. But I experience the issue on a simple playground and development network where I moved er605 in question.  1 eap610 and one er605, no managed switches, no vlan's, they are connected over old 1008MP. ISP provides real public addresses. The CPU and memory are quite the same, no changes in that regard. I only recognized by wireguard's error logs telling me that device does not respond, then tested ports manually and on wan3 they were simply not forwarded. On that location all together 19 ip addresses are used (19 wan's).

 

 

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.

 @Fae  yes, will monitor and if it happens again will write it here. I am not able to reproduce the issue for now too, what is worse is I am not sure since when and how often it happened, I just saw it yesterday in logs, have to read more and see if I can find anything pointing to the issue.
