[PVE-User] CIS Benchmark Fails

[Lucas Gabriel Salvatierra <lucas.salvatierra@edgeuno.com>]

Hello! I have found the following CIS Benchmark fails on PVE:

    2576 - Disable IPv6

Shouldn't PVE have IPv6 disabled by default, and only as an option for those who use it?

    2578 - Ensure packet redirect sending is disabled
    2579 - Ensure IP forwarding is disabled
    2580 - Ensure source routed packets are not accepted
    2581 - Ensure ICMP redirects are not accepted
    2582 - Ensure secure ICMP redirects are not accepted

Furthermore, is packet redirecting required to be enabled by default? Wouldn't this potentially turn PVE into an attack vector?

Cheers
