Subject: Re: IPv6 and Route of Death
My recommendation - check your “Exploitable Port Filter” rules and include IPv6. Test your gear to insure it ‘can’ filter exertion headers.
Read through RFC 9098.
This is an doc on how major ISPs deploy port filtering in their networks. Some are applying RFC 9098.
