I've recently taken up pfSense for my router. Lets you do all sorts of crazy things, like utilize p0f to create OS-specific rules... Don't recall anything exposed in the config ui for proxying web hosts, but its certainly doable, since its just freebsd underneath. I'd wager its also doable with openwrt, though I dunno if apache and mod_proxy might overwhelm memory on such a light-weight box. -- Jarod Wilson jarod-ajLrJawYSntWk0Htik3J/w at public.gmane.org
