[TriLUG] Change "Blocked by xxx" page in my WiFi router [?]

[Carl Crider]

wondering if anyone has been able to do this yet. i have 2 wireless routers
[netgear rangemax & wrt54g]
that i would like to modify slightly. they work just fine as box stock
units, so i havent flashed them
with a *nix version [yet]. anyway, what i want to do is simply change the
"this page has been blocked
by xxx" page that comes up when you attempt to view a blocked site. this
would make my day,
as well as the day of my somewhat picky boss :) i have searched high & low
for an answer, but
have yet to find one.

thanks

carl
