I think you have bigger problems than you think. If your internal network
has direct connectivity from the outside world, such that someone can make a
direct connection from the outside world to arbitrary ports... or even
arbitrary high ports... on arbitrary systems in your network, well, there's
any number of interesting things that are open to attack.

I suggest that you install something more restrictive than a filter... at least
a NAT device like a PIX.

You need something that looks for incoming X connections, incoming SQLNET
connections, and so on. Or you need a firewall.
