I recentely upgraded to the firmware 3.2.17.12_1.4.14 from v3.2.16.22_1.4.9
Although at first glance everything appeared OK, it appears there is a serious disfunctioning has the "port forwarding" parameters are not reliably supported anymrore. I had no problem with the former firware.
My Internet connection is established using PPOE. When rebooting the router everything is working fine: incoming traffic can successfully be routed. However, after a while it is not the case anymore. 😞 If I reestablish the PPOE connection it works again but only for a short while.
I didn't change anything but for the firmware upgrade. I contacted the support of my Internet Service Provider and they said they didn't change anything (of course I am not in position to verify this statement)
The issue seems related to the UpNP feature of the router.
When I esablish the PPOE connection (reboot of router and/or ADSL brtidge) it worked fine for a while. I searched in the Orbi logs and noticed that briefly before it stops functioning ...there is the trace:
[UPnP set event: AddPortMapping] from source 192.168.x.x, Monday, Mar 08,2021 11:04:08
This seems to come from a Foscam camera. Strangely, if I look at the UPnP Protmap table on the Orbi, there is no trace of anything.
I suspect that the UPnP port mapping request of the Foscam camera is leading to a "corruption" of port mappings on the basis of which the router becomes deficient in handling my manua "port forward" rules as well.
This is imho a serious security issue as a single device can lead to a disfunctioning of the router.
If confirmed It is either a problem related to the firmware (as I didn't notice issues before), either a corrupte PortMap table after the firmware upgrade process (which could be resolved by doing a factory reset but I am not eager to do this as it can lead to problems).
From now on, - I disabled UPnP on the Foscam camera (which wasn't an easy task as the process to go to their admin console is cumbersome)
- I disabled UPnP on the router as well
If the issue is disappearing I may consider reactivating the latter
