- | Now with this basic understanding about how the Access Restriction rules in FreshTomato work, we can write shell scripts to control the rules. Below is the script I wrote to enable or disable a rule. Two values are passed on the command line – the rule number and either a 0 or a 1 to disable or enable the service respectively. If you have **jffs** enabled in control panel you can copy the script under jffs directory and schedule it to run, if you want, as a cron job. | ||
