Hello All,

I find out the below message on R80.40 Gateway:

kernel: [<ffffffff91ece20e>] ? vpnk_om_antispoofing_applies+0x4e/0x1b0 [fw_0]

Any idea?

Thank you

Hi,

What is the Security Gateway version - R80.40 clean or with JHF?

Thanks

Hi,

We are running on R80.40 take 87.

Thanks

Thank you.

I will consult a colleague from R&D who handled a similar issue and will update.

Is the Office Mode Anti-Spoofing on for this Security Gateway?

Geomix7 — Mon, 10 May 2021 11:17:06 GMT

No we have disable this option

I consulted the R&D owner and this is probably related to Office Mode Anti-Spoofing.

If you want to find the root cause I suggest contacting TAC, especially if you suspect there's any functionality impact.

If you do contact TAC, it's important to have the following information:

1) In which logs you have observed these errors.

2) What kind of traffic triggers the prints? Is it VPN traffic?

Thanks

Hello Tal,

1) In which logs you have observed these errors.

This message appear in var/log/messages.

2) What kind of traffic triggers the prints? Is it VPN traffic?

I cannot find any more details.

Also, we do not have enable the anti spoofing setting as you mentioned above.

Thanks
