+With Linux iptables, you may use rules similar to the following:
+
+-------------
+iptables -A INPUT -p tcp -m tcp --dport $SERVER_PORT -j ACCEPT
+iptables -A INPUT -p tcp -m helper --helper ftp-$SERVER_PORT -j ACCEPT

+where $SERVER_PORT is the SERVER_PORT defined in uftpd.conf. The first
+rule allows anyone to access port $SERVER_PORT. The second rule
+activates the iptables connection tracking FTP module on port
+$SERVER_PORT.
