RV345P sending out warnings

[michael]

Good evening,

My RV345P is flooding my syslog server with stuff like
   "sequenceId="55"] kernel[520263.051313] fp_netfilter_pre_routing: 6 callback suppressed

Can someone advise me on what this means and how to prevent this warning from happening?

Kind regards, Michael.

[balaji.bandi]

check is the device updated firmware, check full log what causing the issue.

if this is coming from outside, this is more of dos attack, so router not able to handle those time it get this error - just top of my head

once we get more log we can guide what causing this issue.

[michael]

Thanks for the swift reply.
1 - Yes, forgot to mention, the firmware is at the latest available version.
2 - Following the DoS scenario. Could it be the case that there is too much traffic generated internally (streaming, conferencing, ...) that is not handled well by this device? Thus resulting in this warning message.

[balaji.bandi]

chances are there high level, post full log and what kind of traffic you see or monitored ?

[michael]

These are literally my log entries

[balaji.bandi]

what kind of traffic(bandwidth) you see or monitored ?

[NivNiv]

Is there any solution? I have the same problem, tried to upgrade to 1.0.03.21 but still the log full with 2021-04-17T15:08:07+02:00 <warning>kernel: [ 569.214555] fp_netfilter_pre_routing: 15 callbacks suppressed

[michael]

Good evening,

Not realy. Contacted Cisco through Tech Data and the only they could come back with was 'to disable webfiltering alert messages'.
Cheers,
Michael

[NivNiv]

Hi Michael, 

Thank you for the answer, I did try to disable the web filter category in the log settings but still the events are written, I assume the reason is the events written by "Kernel" and not web filter, unfortunately I don't have tech support, do you have any suggestions?

Thanks

Niv

removed. see my next post.

Related to upnp. Disabling it, and those warnings disappeared. Enabling it, they came back.

upnp was the first one, next plugged in Jensen Airlink in wifi ap mode (no router / 4g wan features active even though it has them, just needed one additional wifi ap for testing purposes) , next thing I know this happens
