mainly used in start-up script
When we play with iptables aka firewall we might end up in situation, where we execute rule, which has unforseen impact - lock yourself out. Recovering from this situation is necessity.

- Enable reboot via SMS.
- Test all commands in shell first before putting them into Start-up script. This way the command will be wiped out, when unit is rebooted.
