could you please tell me an easy way of installing a firewall on my linux box?

Redhat 7.3
kernel 2.5.32

tried pmfirewall, but when i start ipchains, it says incompatible with the kernel. I tried kernels 2.4.18 nad 2.4.19 with no success.

did you compile iptables support into your kernel under Networking options?

yes i did. However, i would like to know, what firewall most people use

Hi,

You could use PMFirewall to start of with, I found it very straight and satisfactory.

any comments any one ?

Cheers !!:)

For the 2.2 kernels, you want to use ipchains.
For the 2.4 kernels, you want to use iptables.

Netfilter/iptables makes a fine firewall. :)

With iptables you can take care of those FTP and DNS issues with your firewall ruleset that you had with ipchains.
