    I have installed and configured a simple wireguard vpn network on ubunto. I have created multiple peers and everything works fine. Peers can ping each other and the host on the container network wg0. The host can't ping the peers from outside the wg-eady container. but if I ping from inside the container on the host using udo docker exec -t -i wg-easy ping {peer ip} it is possible. What I need is to be able to ping the peers from the host on ec2 instance.

    I have a windows VM server running in the Azure cloud. It is the 2BS with 2 VCPUs and 4 gig of RAM. It is running SQL Express and a few websites under IIS.

    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.
