 Netris supports ACL-based network access control on managed switch fabrics. Each entry you configure — an ACL entry — matches traffic by source and destination IP address, port or port range, and protocol, and applies a Permit or Deny action.

 Why Air-Gapped Installation?
 ----------------------------
 In many production or regulated environments, network connectivity is tightly restricted for security or compliance reasons. An **air-gapped** environment prevents unauthorized external access and ensures no reliance on external artifact repositories. All required components—binaries, container images, and Helm charts—are transferred manually (e.g., via USB, secure copy) and installed entirely offline. This approach:

 Netris IPAM is the address-space source of truth every address-consuming object in Netris depends on: V-Net gateways and DHCP pools, NAT and L4 Load Balancer address pools, switch and SoftGate loopback and management IPs, and BGP route advertisement all draw from subnets created here first. Allocations and subnets are tracked per VPC in a nested, tree-like structure, and each subnet's purpose and tenant determine which services are allowed to consume it.

 Link Aggregation (LAG), also known as link bundling, Ethernet/network/NIC bonding, or port teaming, is a method of combining (aggregating) multiple network connections in parallel to increase throughput beyond what a single connection could sustain and to provide redundancy in case one of the links fails.
