I see the line for your DSL router or whatever 192... is. What is your goal? You can inadvertantly block your DNS server that way, for example.

Do not forget that you can render the system almost unusable with one single "interesting" line in your script. If you have iptables enabled now and have access - keep a copy of the current setup.
