    I would personally recommend using a firewall as well, simply because 'hackers' can spoof an internal IP address (whihc is usually detected by the router) and use access things on your network as if they were plugged in.

    Yeah...Its better to have a Software firewall or Host based software. Coz say for example you have received a worm zipped in a file or a port scan from a spoofed source then ZA can do a better job ...the best part of Host Based ( ZA) is it can alert the out going requests as well...
    I recommend keeping it..
