... i don't know how to do this via webrick, but u find out the 
remote_ip that required the request in the app code simply so:
request.remote_ip

so u could do something like

class SomeController

before_filter :block_localhosts

def action1
end

def action2
end

def block_localhosts
if request.remote_ip=~/127\.0\.0\.1/
return false
end
end

end

in the example above, all requests coming from 127.0.0.1 won't be 
rendered.
hth :)
