What I need is to be able to ping the peers from the host on ec2 instance.

Unfortunately it runs like a dog and always appears to have close to 100% CPU usage. I have no idea why the cpu is so maxed out some of the time. If you have the experience and can help let me know. You will need a rating of no less than 4.9 for me to reply. Thanks

    Hi I was having an issue logging in with the server today with Putty. After trying a couple of times, and restarting the server, still, the login error didn't go. Then I rolled back the server on the previous date Snapshot and then I am getting a error message on the contabo side. Attached the error message. I also need the person to verify the storage is a SSD or NVMe? If you know to customise the server for the best performance then I would need this as well.

I wouldn't mind doing a fresh install of my raspberry pi with whichever packages you suggest. I want to set up pihole and wireguard on my raspberry pi as a server. I have a dynamic ip and I would like to have that automatically update with the hostname of a ddns. I would also like a firewall within my raspberry pi to be more secure.
