IPTables configuration problems and OpenVPN setup issues.
You're facing challenges configuring OpenVPN with iptables on Ubuntu 18.04. The main problem seems to be that your rules aren't applying correctly. You've set up a setup where all traffic over OpenVPN should be blocked except for port 3389, but you're not seeing the expected behavior. It might help to double-check your iptables rules and ensure they're being applied properly. Also, verify that the OpenVPN configuration itself is correct and that you're using the right ports. If issues persist, consider reviewing your firewall settings and testing with a simpler configuration first.
Confirm if eth0 is the correct name for your physical network adapter. This applies when you paste iptables commands without modifying them.
