Is your feature request related to a problem?

  • Yes

    Problem Description:

    Currently, the system is unable to accurately reconstruct the original source of incoming packets. This is because all incoming traffic is marked as originating from the XDP address, rather than preserving the actual source address. This limitation hinders network observability.

    Solution:

    Investigate and potentially implement the use of cgroups v2 to better track both incoming and outgoing network traffic
