I was reading this article → Hidden Onion Service using Tor, nftables and NGINX | by Marcus Cvjeticanin | Dev Genius
and I can read
Then we add a rule to accept loopback interface traffic.
sudo nft add rule inet filter tor_chain iif lo counter accept
So does Onion Services require this ?
is there a way in NFtables to specify that only Tor daemon (Onion services) can use the loopback ?
