RE: Firewall on server itself

Since you are calling this a secure web server, I'd use iptables to block
incoming traffice to all ports that you don't explicitly allow, fewer
surprises that way.  Being paranoid isn't all bad.

Subject: Firewall on server itself


I am trying to set up a secure web server which will already be protected
by a dedicated harware firewall.  The hardware firewall will be configured
to protect the web server as well other computers on the network.  The
web server will be running Red Hat 9.0.  Is there any reason to install
and configure firewall software such as IPTables on the web server itself?
Are there any advantaqes or disadvantages to having two firewalls set up
this way?

Thanx in advance for any help.
