This is an updated iptables that allows local connection (192.168.1.0/24 assumed) to FTP (vsftpd), Webmin, and Samba, as well as the ports needed to allow remote access to your EQEmulator and Apache. Also includes some protection against DDOS to port 80.
I would have updated previous post, but will not allow me to edit.
