[RndTbl] Routing questions

[Dan Keizer]

yeah -- like Bill says -- you want to use a customized firmware to
perform that function.

Check out a few micro builds ... a couple I've used are below -- you
didn't say what hardware you have, but check the following:

dd-wrt:  http://www.dd-wrt.com/wiki/index.php/Supported_Devices
openwrt: http://oldwiki.openwrt.org/TableOfHardware.html

you would probably like dd-wrt -- it is very user friendly and
provides alot of functionality ... a small screenshot of one of my
dd-wrt router configs is attached -- (I don't have that service
enabled)

openwrt has a large collection (and I mean large!) of downloadable
programs cross-compiled for the various supported platforms... both
have ssh and http control.

Dan.
