IPID

IPID rewriting sets the IPv4 Identification field to 0.

yaml

l3-rewrite:
  ipid: true

In the NFQUEUE path, UA3F parses IPv4 packets and zeroes the Id field. IPv6 packets are not modified because they do not have the IPv4 ID field.

With eBPF acceleration enabled, UA3F selects the set_ip_id_zero TC program.
