In m0n0wall 1.8.1, the base system has been switched to FreeBSD 8.4 for better support of recent hardware.
Thanks to contributions by Andrew White, Lennart Grahl and Pierre Nast, there have been significant improvements, new features and bug fixes in many areas.
This version requires at least 128 MB RAM and a disk/CF size of 32 MB or more
Change log highlights (see the SVN change log for the full details):
add scheduler ("Croen") service with many different job types (enable/disable interface or shaper rule, Wake on LAN, reboot, reconnect WAN, execute command etc.)
improved IPv6 support, including IPsec, DHCPv6-PD, RDNSS and DNSSL, and NDP info on the ARP diagnostic page
major overhaul of wireless LAN support. On some cards, it is now also
possible to create multiple APs at the same time. To reflect this
change, the wireless settings have moved to the Interfaces: assign
page, where WLAN subinterfaces can be created much like for VLANs.
DNS forwarder: add option to log DNS queries, add aliases (CNAMEs) and MXs
Add AES-256, SHA-256/384/512 and additional DH group options to IPsec
Make rule moving and deletion on shaper rules page work like for firewall rules.
Initial support for USB modems
enable CPU hardware crypto support
automatically reassign available physical network interfaces if none
of the assigned interfaces in the configuration can be found on the system
(i.e. for a new installation, or when moving an existing config to new
the "embedded" image is gone; generic-pc-serial should now be used for PC Engines and Soekris boards
console speed for serial images is fixed to 9600 baud (no longer tries to use BIOS preset value)
introduction of an automated build system that allows one to build m0n0wall from scratch with
almost no manual intervention on a standard FreeBSD 8.4 system
countless bug fixes and improvements in UI and system configuration code
