Linux network namespaces isolate the network stack for a group of processes.
Each namespace has its own network interfaces, routing table, ARP table, firewall rules, and sockets.
- Interfaces (veth, physical NICs, bridges, etc.) can be moved or created inside a namespace.
- Processes in different namespaces cannot see each other's network interfaces or traffic.
- Namespaces can be connected using veth pairs, bridges, or routing/NAT.
They are widely used by containers and network virtualization systems to create isolated network environments.
This feature is available on Artica v4.50 Service Pack 7 or Artica v4.50 Service Pack 6 Hotfix 20260315-01
To improve security, Artica is progressively making its services compatible with network namespaces.
In this first release, you can containerize the web administration console.
