Can't access to ssh after configure OpenVPN Client

Question

I followed a guide to configure my raspberry to connects to PureVPN server following this guide : How to Setup PureVPN on Raspberry Pi.

I Followed the part regarding OpenVPN. After the configuration I can't access to the Pi through SSH. I removed the installed package and I restored the IP tables but nothing happens.

Check SSH

Make sure that your ssh server is running properly.

1. Connect to your Pi with a keyboard, mouse and monitor (or other)
2. Check your Pi's ip address
ip a
3. Check that ssh is running
   sudo systemctl status sshd.service
   or
   sudo /etc/init.d/ssh status
4. Check that iptables is not blocking ssh traffic
   iptables-save
   (no output is a good sign).

Undo The Changes

Make sure you undid all of the changes.

1. Uninstall the packages that were installed:
   (If they weren't installed already, of course).

   sudo apt-get remove dnsmasq openvpn iptables-persistent
   

2. Undo the changes to the config files:
   (This step is easy if you backed up your config files before changing them).

   /etc/dnsmasq.conf
   /etc/openvpn/auth.txt
   /etc/openvpn/server.conf
   /etc/logrotate.conf
   /etc/sysctl.conf
   

3. Undo the changes the vpn_client_gw_script.fw script made.
   (Running scripts that alter your system always carries risks).

Nuke And Pave

If that doesn't work, reinstalling Raspbian will fix ssh.

1. Back up all of your data
2. Copy a fresh image of Raspbian onto your sdcard
