No; firstly the "localnet" ACL is defined by *source* address, therefore 
"localnet" matches traffic *from* your local network.

Secondly the ! negates this, therefore "!localnet" matches any source address 
which is *not* in your local network.

Therefore "http_access deny !localnet" denies any access from an address not 
in your local network.

This then allows access from any address which *is* in your local network.

Now, having matched all traffic not from your local network, and all traffic which 
is from your local network, you have accounted for all possible traffic, 
therefore any other rules have no effect.


Hope this helps,


Antony.
