ok basically, i have got apache working on my server now (i have been using linux for about 3 days) and i have installed and setup php and mysql
but now i want to secure the server. I have heard about iptables and ipchains, and have looked at several websites about it, but basically dont understand it
can i download, or even buy a firewall instead of using ipchains and iptables?
If so, what are good firewalls, free would be good, but if not, i will also pay.
please note, its a personal server, im not going to be hosting for anyone, just myself
