NAT & Connection Tracking

NAT and conntrack sit on the packet path of every Linux box, and most outages blamed on 'the firewall' are really conntrack. Change the NAT type, connection rate, table size, port range and timeout and watch the server-computed conntrack table fill, the SNAT source-port ceiling, MASQUERADE's per-packet cost, and the asymmetric-routing correctness trap — validated against Linux v6.12.93 netfilter (nf_conntrack_in / nf_nat_manip_pkt / nf_conntrack_tuple_taken).
