what kind of firewall i should have on fedora core 2?

All distributions use the iptables firewall which is part of the kernel. There are a number of ways of configuring iptables. Fedora Core probably has a graphical configuration tool however my preferred method is to set up the rules with the iptables command (see man page for details) and using "iptables-save >/etc/sysconfig/iptables" to save the settings. Mandrake (and I presume Fedora Core) will run iptables-restore at boot up to load the saved rules.

ok so i don't need any other firewall i already have that setup thank you

The basic Fedora GUI for Iptables is at - System settings - Security level - however if this isn't sufficient try Firestarter on Fedora.
