* Version 0.1 Initial version of natd. * Version 0.2 - Alias address can now be set by giving interface name with new (-n) command-line option. - New Makefile based on bsd.prog.mk. - Error messages are written to syslog after natd has become a daemon. * Version 1.0 - Support for using only single socket (-p option) * Version 1.1 - -a option now understands a hostname also. - -a option no longer dumps core. - Packet aliasing software upgraded to v. 1.9 - added long option names (like -address) * Version 1.2 - Fixed core dump with -port option. - Added -Wall to CFLAGS and some headers added to natd.c to get clean compile by Brian Somers [email@example.com]. * Version 1.3 - Aliasing address initialization is delayed until first packet arrives. This allows natd to start up before interface address is set. - SIGTERM is now catched to allow kernel to close existing connections when system is shutting down. - SIGHUP is now catched to allow natd to refresh aliasing address from interface, which might be useful to tun devices. * Version 1.4 - Changed command line options to be compatible with command names used in ppp+packetAlias package (which is the original application using aliasing routines). The options which map directly to packet aliasing options are: -unregistered_only [yes|no] -log [yes|no] -deny_incoming [yes|no] -use_sockets [yes|no] -same_ports [yes|no] The short option names are the same as in previous releases. - Command line parser rewritten to provide more flexible way to support new packet aliasing options. - Support for natd.cf configuration file has been added. - SIGHUP no longer causes problems when running without interface name option. - When using -interface command line option, routing socket is optionally listened for interface address changes. This mode is activated by -dynamic option. - Directory tree reorganized, alias package is now a library. - Manual page written by Brian Somers <firstname.lastname@example.org> added. - README file updated. * Version 1.5 - Support for sending ICMP 'need fragmentation' messages when packet size exceeds mtu size of outgoing network interface. - ipfw rule example in manual page fixed. * Version 1.6 - Upgrade to new packet aliasing engine (2.1) - redirect_port and redirect_address configuration parameters added. - It is no longer necessary to quote complex parameter values in command line. - Manual page fixed (same_port -> same_ports). * Version 1.7 - A bug in command-line parsing fixed (it appeared due to changes made in 1.6). * Version 1.8 - Fixed problems with -dynamic option. - Added /var/run/natd.pid * Version 1.9 - Changes to manual page by Brian Somers <email@example.com> integrated. - Checksum for incoming packets is always recalculated for FreeBSD 2.2 and never recalculated for newer versions. This should fix the problem with wrong checksum of fragmented packets. - Buffer space problem found by Sergio Lenzi <firstname.lastname@example.org> fixed. Natd now waits with select(2) for buffer space to become available if write fails. - Packet aliasing library upgraded to 2.2. * Version 1.10 - Ignored incoming packets are now dropped when deny_incoming option is set to yes. - Packet aliasing library upgraded to 2.4. * Version 1.11 - Code cleanup work done in FreeBSD-current development merged. - Port numbers are now unsigned as they should always have been. * Version 1.12 - Typos in comment fixed. Copyright message added to source & header files that were missing it. - A small patch to libalias to make static NAT work correctly. * Version 2.0 - Upgrade to libalias 3.0 which gives: - Transparent proxy support. - permanent_link is now obsolete, use redirect_port instead. - Drop support for early FreeBSD 2.2 versions - If separate input & output sockets are being used use them to find out packet direction instead of normal mechanism. This can be handy in complex environments with multiple interfaces. - libalias is no longer part of this distribution. - New sample configuration file from Ted Mittelstaedt <email@example.com>. - PPTP redirect support by Dru Nelson <firstname.lastname@example.org> added. - Logging enhancements from Martin Machacek <email@example.com> added.
