I've basically just joined a new company as head of IT - needless to say, I've been left with some rather screwed up software [and hardware] due to an incompetent predecessor. One of our major problems is a 7 year old desktop running a 4 year old version of Linux as a firewall. Now the original installation I'm told, was pretty tight - as such, I want to transcribe the old IPTables rules onto the new machine.
Is there a way of doing this - seeing as I'm not particularly au fait [yet] with Linux 7.2 or Fedora? If not, how can I see what the original rules were?
