I need to open the port range 3000 until 4000 in the Kiss firewall because they are used for Ruby on Rails. I tried to open them like this 3000_4000, but as soon I start Kiss i get this message:
iptables v1.2.11: invalid TCP port/service `3000_4000' specified
Try `iptables -h' or 'iptables --help' for more information.
