There is no path on the website to find the snapshots at
http://m0n0.ch/wall/snapshots/1.8.2/ other than search the forums. I know they exist and I had trouble finding them.

Also, the website is unclear on how to build m0n0wall from scratch now. There is no link on the repository page to
http://svn.m0n0.ch/wall/branches/freebsd8/build/scripts/README and
http://svn.m0n0.ch/wall/branches/freebsd10/build/scripts/README
