Please find attached all the info you requested. Hope it helps.
Also, here's the nft script I'm using to trigger the issue locally:
#!/usr/sbin/nft -f
flush ruleset
table inet filter { chain input { type filter hook input priority 0; iif lo accept ct state established,related accept tcp dport { 22 } ct state new accept ip6 nexthdr icmpv6 icmpv6 type { nd-neighbor-solicit, nd-router-advert, nd-neighbor-advert } accept counter drop } }
Cheers, -- Luis
