This section covers all networking aspects of your Lobster Cloud environment. It provides you with detailed information on available communication ports, VPN connectivity, DNS configuration, firewall rules, and SSL/TLS certificate management.

Every Lobster Cloud system runs within a dedicated AWS Virtual Private Cloud (VPC) with its private network range. Incoming connections are controlled via AWS Security Groups (firewall rules), while outgoing connections are open by default to allow communication with your partners, APIs, and external systems.
