IPv6 connectivity issue with EIS 17.1.13.0

Hi,

Previously I had IPv6 connectivity issue when HTTP/3 scanning is enabled with EIS 17.1.9.0. After updating to 17.1.13.0 the issue was gone. But now it happens again. I assume it is because of the updated Internet protection module (1475.3, build date 6/26/2024 as of now).

When HTTP/3 scanning is enabled, pinging IPv6 addresses will not work or work with high packet loss. Disabling it fixes the problem. I recorded a video to demonstrate the issue, and captured network packets using Wireshark, collected logs with traffic scanner advanced logging turned on.

The screen record is in MKV format and it can't be uploaded directly, so I put it in a zip archive.

Does the issue persist after switching to the pre-release update channel with the firewall module 1449?

Thanks for your reply. Finished updating just now and the issue is gone with the pre-release version.
