ipV6 flood

Hi

Here's a quick screenshot of the logs:

This is flooding my network, and making it slow and unstable.


I have tried to block all IPv6 traffic, but no luck.

I also block ping requests against that particular ipv4 ip. Nothing.

What can I do?

Harvy66:
I wonder if the pinging is harming your network or the logging is. Just looking at the screenshot, it's like 2-3 pings per second.

JKnott:
Perhaps I'm missing something, but I only see one IPv6 item and all the rest IPv4. 

Derelict:
That is an insignificant amount of traffic to be fingered as causing any kinds of slowdown.

xkaas:
Hi anyone.

Yes. You guys were right. That is nothing.


Take a look at this screenshot:

You see - That isnt alot of traffic either, However, its enough to slow my firewall down.

The actual pipe only uses a few mbits of traffic. The stable table size is on 500.

I use PFBlocker to block these connections. I cannot change the port, as its used for a game service.

Is there anyway, I can minimize the impact? I guess its just quite large packets its sending.

I've been thinking about upgrading the firewall with a way better CPU. Would that help my issue?

I am unsure, if this is not what is causing the lagg. As I have a device connected to the network that is not going through the PFsense box which is working just fine, and a speedtest also shows around the speeds I pay for. Therefore, I am pretty sure its the box itself getting bombed with something. CPU sometimes spikes from 10% to 50% then down again slowly. Up and down.
