On firewall_nat_edit.php, the custom port box for "Redirect target port" doesn't get grayed out when an option is chosen from the drop down. It should behave the same as "Source port range" and "Destination port range" on that page - if something is picked from the drop down (say, HTTP), then the Custom box gets grayed out.

This snippet looks like it's trying to do that.

                if (($('#localbeginport').find(":selected").index() == 0) && portsenabled) {
                        disableInput('localbeginport_cust', false);
                } else {
                        $('#localbeginport_cust').val('');
                        disableInput('localbeginport_cust', true);
                }

but it doesn't actually disable/enable the field.
