ipfwadm rule

[Pere Camps <pere@casal.upc.es>]

Hi!

	I'm trying to set up my home box (connected via PPP to the
internet to do the following):

	a) Deny everything incoming (tcp,udp,icmp)
	b) Accept only DNS udp connections
	c) Accept incoming tcp data for only the connections that I have
initiated.

	So far I've got this working:

	a) no problem
	b) I accept udp connections from the domain port to the 1024:65535
	c) I accept tcp connections from any port that's below 1024

	Problems:
	c) They can still telnet me if doin'g it as root. The same for b).

	Does anybody know the right ipfwadm rule for what I want and even
if this setup is possible?

	TIA!
