Does anyone now what this means in my logs.
Is that in the firewall log?
What pfSense version?
It looks like a badly parsed log entry or maybe a badly formed rule.
Try setting the firewall log to raw. That should tell you more.
Thanks for reply Steve and it was in the firewall logs, It only appeared about 10-15 times that day that I am aware of, Its only that I have never seen it before so I thought I would ask because someone might now what it means and I have checked logs regularly since posting and it has never happened again.
I am on latest stable version 2.4.3-p1
I will look in to how to set firewall logs to raw.
Hit the wrench top right from the firewall log page and it's an option there in 'Manage Firewall Log'.
It's likely nothing to worry about though.
