How to install and configure a firewall on Red Hat 9 linux

Hello everyone

I've installed Red Hat linux 9 and have configured it on my LAN/internet.

I didn't install ANY firewalls because i wanted to do it myself so as to become familiar with the security subject and firewall configurations on Linux.

I've no clues about linux firewalls/security.

Please guide me in terms of what firewalls 2 use(which firewall is generally good in all) configurations and maintainance.

Lemme me know if you have good any urls 2 look into etc on the subject and where to take a start from.

Hello Everyone

To start with things:

1.I would like to control the ports on my pc first(SSH,FTP TELNET,eth0)

2.Define the basic firewall rules(Medium,High etc)

I'm not running my machine as an internet gateway.I'm using it as a machine behind another linux machine acting as a gateway.

Another option if you really want to play around with this is to look at the iptables command. Reading the man page should be a good place to start. Most Linux firewall tools are just front ends for iptables. Iptables is the user space tool that manipulates the kernel's packet filter. There are also plenty of resources on the Web for configuring iptables to do various things.
