Setting up OpenVPN now lost internet connection

Installing and Using OpenWrt
1

Hello,

I was following this exact guide here and after finishing and rebooting my router I had no access to the internet. Could someone please help a noob undo whatever the commands in te link did to make me lose connection? I wish I backed up my settings beforehand!

I uninstalled the openvpn-openssl & luci-app-openvpn packages and change back to default dns but it didn't fix it. In the link above I notice step 4 mentions there's 2 was of doing this and they don't recommend doing them at the same time, are they referring to both step 4 and 5 because I did them both.

I noticed there was a "lan to vpn" rule in the firewall which I changed to "lan to wan" and it seems to have fixed it. Much easier knowing what's going on through the GUI..

This means your VPN connection is likely failed, check the system log.
