ISPconfigs Firewall adding Port range? Hey! I just installed GLFTPd. The site is working fine when I have the firewall turned off because of the passive ports, but when I turn it on I can't list anymore. So I added the correct line(s) in the config to make it only use a selected port range for passive mode. But my question now , is there a way to use the Firewall page under ISPConfig's Management Tab to add " Port Ranges " and not just a single port?
