This is the documentation for my AWS site-to-site VPN deployment in my homelab. The three sites have three different edge endpoint devices that will be the customer gateway for the site-to-site VPN. The first site uses a FortiGate firewall as the customer gateway. The second site uses a Palo Alto firewall as the customer gateway. The third and last site uses a Cisco Router as the customer gateway. The cloud site AWS side will utilize AWS Site-to-Site VPN using customer gateway, target gateway (virtual private gateway), route tables and site-to-site VPN connection (with IKEv2 tunnel). After successfully implementing the connection on every site, each of the sites will be able to access the cloud site’s AWS network and resources.
