I'm using OS X Snow Leopard and typed this cmd into Terminal after reading a blog post that claimed it was a fix for a particular problem I was having, but it has caused other config issues instead. Is there a way to reverse/undo entered commands in Terminal?

This is the code I entered:

iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-ports 10000

Any help appreciated.

You have to learn how to delete a rule from the list. You cannot simply "undo" a command. (and this is not a programming related question). – Felix Apr 23 '12 at 0:12

No, it would be quite too complicated for Terminal to know how to undone every possible command... Despite that some commands can't be undone.

In your case, I think it's something like iptables -t nat -flush or so. But just read the iptables manpage.
