RE: Help Needed: i want to make a firewall

Get you a copy of Smoothwall.  www.smoothwall.org
There are manuals on this site.  It's pretty straight forward and fairly
secure.
It has a nice remote web administration page where you can set up rules and
stuff.
Hope that helps

Subject: [Snort-users] Help Needed: i want to make a firewall


i want to make a firewall for a network. say i have
two interfaces (NICs) on a PC 

one connected to my private network and other to the
internet. can i use 

libpcap/wpcap to capture all the packets and then
filter all the packets according 

to some user defined rules and then drop the packets
violating any rule while 

leting others go. currently i know that libpcap/wpcap
can only be used to sniff 

packets but cannot block packets going into the IP
stack of an OS. i want that i be 

able to block all the packets and let go (into the
protocol stack) only the packets 

which donot violate any rules hence making a packet
filtering firewall.

can anyone tell me how to achieve this with pcap or
with anything else.

need an urgent reply please.
