My system admin gave me a file with iptables rules. What command do I type in to load this?

I watched him do it before, and he did it in 1 line! Something like...iptables > thefile.dat ????

  2. You load an iptables configuration file using iptables-restore

    iptables-restore thefile.dat

    This has effect immediately. However for this settings to be persistent over system reboot they must be saved. On most distributions this can be done with.

    /etc/init.d/iptables save

    As mentioned in other answers the configuration can be saved using

    iptables-save > thesavefile.dat

    The file itself is a text file and can be edited with any texteditor and then reloaded into iptables using the iptables-restore command.
