* 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 [brian@awfulhak.org].
* 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 <brian@awfulhak.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 <brian@awfulhak.org> 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 <lenzi@bsi.com.br>
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 <tedm@portsoft.com>.
- PPTP redirect support by Dru Nelson <dnelson@redwoodsoft.com> added.
- Logging enhancements from Martin Machacek <mm@i.cz> added.
