Network

Networking on LANIT Cloud is built from these components:

• Network / Subnet — virtual private network and the IP range for VMs.
• Router — routes between Networks and out to the Internet (External Gateway).
• Floating IP — a public IP attached to a VM for inbound access from the Internet.
• Security Group — stateful firewall at the network layer, per VM / interface.
• VPN Gateway — site-to-site IPsec to an on-premise network or another cloud.

A typical topology: VMs live in a Subnet, all outbound traffic goes through the Router (S-NAT), inbound from the Internet enters via a Floating IP and is filtered by a Security Group. Use a VPN Gateway when you need internal connectivity to a network outside LANIT.

Network Interface

Create Networks and Subnets with CIDR / DHCP / DNS to provide internal IPs for VMs.

Router management

Enable External Gateway, attach interfaces from each Subnet and configure S-NAT.

Floating IP

Allocate a public IP, attach it to a VM and adjust the Internet bandwidth.

Security Group

Control inbound/outbound traffic by port and source IP with stateful firewall rules.

VPN Gateway

Site-to-site IPsec between LANIT Cloud and an on-premise network or another cloud.
