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?



  • 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.



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

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



  • 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.

    No, it is not.
