Amazon VPC Reachability Analyzer now allows you to view the network reachability between your source and destination in your virtual private clouds (VPCs) through Gateway Load Balancers, AWS Network Firewalls, and AWS PrivateLink services. In addition, you can also check network reachability between a source resource and your specified destination IP address. 

Reachability Analyzer is a configuration analysis tool that enables you to check network reachability between a source resource and a destination resource in your virtual private clouds (VPCs). With support for Gateway Load Balancers and AWS Network Firewall, you can now check whether the network reachability between your source and destination is potentially being blocked due to a firewall rule in your AWS Network Firewall or firewall appliance behind the Gateway Load Balancer. You can also trace and troubleshoot network reachability to AWS PrivateLink services and their target EC2 instances within your AWS Organization. Lastly, you can now trace and troubleshoot network reachability across your VPCs to hosts based on their IP address. In cases where destination IP address is outside AWS, Reachability Analyzer determines reachability between the source and the relevant network gateway on AWS such as an Internet Gateway or AWS VPN Gateway.
