"Called Tomato, it is the name of a firmware for wireless
routers, including the popular WRT54G family. Tomato is designed to
be flashed onto your compatible wireless router to replace the
stock firmware loaded by the vendor."
"Like DD-WRT, the Tomato firmware can be installed on a variety
of wireless routers. Tomato supports the Linksys WRT54G family,
which also includes the WRT54GS, WRT54GL and WRTSL54GS. Note that
Tomato will not work with WRT54G routers later than version 4."
"Unlike DD-WRT, which is available in numerous versions for
different routers and with different feature sets, there is only
one primary version of Tomato. There is also one alternate version
compiled specifically for the Buffalo WHR-G125 router."
