Hi
What about backdoor issues?
>From what I understand, with packet filters, stateful or not, a trojan
horse could open a connection to the outside world on a given port
(if it's permitted of course), and establish contact with the cracker's
system.
That would be less easy to do with application gateways, for which
specific processes should be implemented.
Am I wrong?
