I think you'll have to use custom rules or do it from the command line (always check a custom rule at the command line first). Google for "man iptables" for lots of references and look for multiport. You'll want something like;
| Code: |
iptables -I WHATEVER -p tcp -m multiport --dports 14300,14400:14406,14500:14600 -j ACCEPT
|
For WHATEVER, you'll probably want INPUT, OUTPUT or FORWARD but I cannot tell from your screenshots what type of rule you are trying to add. You may also want to specify an interface (either -i or -o) or perhaps IP address (-s or -d). I must stress you need to check the rule at the command line first.
