Well, as far as I know, iptables can do all the things you have mentioned.
May want to take another look.

Hello All.

I don't generally broadcast messages, but I'm thoroughly frustrated and
could use your help

I need to put up a "fully functional" Linux firewall. I've done the
ipchains/portfw/ipmasqadm solution on Red Hat 7.0 (2.2.19 kernel) and am
neither convinced that this is a "robust" solution nor that it is relatively
easily maintained. I've read and read and read and haven't come up with a
more lucid solution.

I need to construct a firewall to do the following:
  o NAT in and outbound traffic
  o Filter IP traffic
  o Block basic attackers (SYN, SMURF, etc)
  o Log and report denied traffic

I'm not (necessarily) adverse to purchasing software, but I'd rather use
open-source if possible.

Any help is greatly appreciated.
Thanks,
-=Berns
