What should be written in the terminal after creating a script to redirect traffic in order to return the original routing?

Question

iptables

I have UBUNTU 14.04 installed. I recently came across an interesting article on redirecting all traffic through TOR, here at this link https://cryptopunks.org/article/forward+all+the+tr... . Before that, I used VPN'om, given that at the end of the article there is an instruction for returning the settings to their original position, I decided to do it, see how it all works. But when I decided to do everything back, I registered all the commands in the terminal to roll back the settings to their original state, but nothing worked. postimg.org/gallery/w6bwh4sc- here are the screenshots from what I entered to return the settings. The Internet starts only through the Tor browser, even after executing these return commands, the vpn does not connect, I want to return everything back so that the Internet works not only through the Tor. I switched to ubuntu just a couple of days ago from Windows, I’m still very poorly versed in it, but I really hope that they will help a beginner with a solution to this issue.
