Changes from 2.2.x

• Connection tracking support.

• Full Network Address Translation (NAT) support.

• New userspace utility (iptables) replaces ipchains and ipmasqadm.

  • iptables syntax mostly compatible with ipchains.
  • New modular architecture allows the use of ipchains and ipfwadm (with a limited feature set) by loading the appropriate module (ipchains.o or ipfwadm.o).
