I am having trouble getting a site to site VPN working from AWS to an UDM Pro. I have standard VPC setup with one public and private subnets. The public subnet has the Linux EC2 Ubuntu instance with wireguard installed. The private subnet has its route set as a second interface on the EC2 instance. The wireguard EC2 instance can connect to the UDM pro and ping devices behind the UDM pro in private subnets. However, devices behind the UDM pro cannot ping servers in EC2. Any suggestions as to things I should look at?
