Yeah except it would be iptables-restore < old_fw_rules.bak

Fun fact: When you do iptables-save, you have to redirect the output if you want to save it to a file. But when you use iptables-restore, you don't need to pipe it back in, you can just use the filename!

Totally! I still catch myself doing that sometimes. Old habits die hard
