First here is the list by the system in question, working once the ipv6 module is blocked from loading at boot. Next is the list from a system with identical hardware and near-identical configuration (same firewall rules), but with ipv6 loading - and which also has only 4 of the 6 NICs showing up in the ipv6 proc conf space, and also has NAT (in this case DNAT is what I tested) failing - also where the NICs on the Internet side of things are those coincidentally not showing up with proc ipv6 conf settings. As to the output of /proc/net/nf_conntrack, you just want to see anything, or under specific load? I'm not going to just publicly post the raw data - although both systems have some there - since IPs can identify my client and their clients, which would violate confidentiality.
