Hi Menon, > I was very busy with studies yesterday. But I got to install > firewall builder.

Best method for beginners is: - define objects in your environment, such as networks, hosts, etc. - add a firewall - use the wizard to make a basic configuration of this firewall - fine tune your rules by adding more objects and/or rules > I get some errors too. I can't really help you with the errors. Did you install from rpms? Did you install the iptables-extensions-rpm (something like fwbuilder-ipt....). As another user suggested, ask for help about these errors on the fwbuilder.org site (forum, mailinglist). I can confirm that the author is very responsive and will help you. -volker -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
