See man iptables, specifically the raw table:
raw:
This table is used mainly for configuring exemptions from
connection tracking in combination with the NOTRACK target. It
registers at the netfilter hooks with higher priority and is thus called
before ip_conntrack, or any other IP tables. It provides the following
built-in chains: PREROUTING (for packets arriving via any network
interface) OUTPUT (for packets generated by local processes)
