19. Network gateways

Network gateways connect SDN Private Networks to external IP networks. Gateways have VPN and NAT functionalities that can be enabled either separately or at the same time. The VPN functionality offers a way to establish encrypted connections using site-to-site IPSec VPN connections between SDN Private Networks and remote networks. The NAT gateway functionality enables outbound Internet connections from Cloud Servers in SDN Private Networks.

The network gateway service is attached to an SDN router. It can be utilized by one or more SDN private networks attached to the same router. For traffic to land on the network gateway your servers must have the SDN router as their next hop for any destinations you wish to route through the network gateway service.

Available features

Feature	Description
nat	NAT gateway is a Network Address Translation (NAT) service that offers a way for cloud servers in SDN private networks to connect to the Internet through the public IP assigned to the network gateway service
vpn	VPN gateway is a Virtual Private Network (VPN) service used to establish an encrypted network connection when using public networks

Tunnel operational state

The tunnel operational state indicates the tunnel's current operational, effective state. Managed by the system.

State	Description
idle	Connection is idle.

unknown	Connection is in an unknown state.

Tunnel health

{tunnel_up} is true if the tunnel is "up", that is an IPSec SA has been established, false otherwise.

{tunnel_healthy} is true if there haven't been "bad" log messages for the tunnel in last five minutes, false otherwise.

Attributes

Attribute	Default value	Accepted value	Required	Description
uuid		Valid UUID	no	The uuid of the tunnel.
name		1-64 characters, regexp pattern ^[a-zA-Z0-9_-]+$	yes	The name of the tunnel must be unique within gateway.
local_address		Local address name object	yes	See local address.
remote_address		Remote address object	yes	See remote address.
ipsec		IPSec object	yes	See IPSec for more information.
tunnel_internal_ip	""	IP address or "" (unconfigured)	no	Tunnel link-local address (inside tunnel IPv4 address). Used for example by the tunnel internal pinger feature.
internal_peer_ping_interval	0	Peer ping interval in seconds	no	See description below in Tunnel internal IP and the pinger.

Tunnel internal IP and the pinger

{tunnel_internal_ip}, when not empty, must be the second or third address in a /30 network in the 169.254.17.0/24 range and must not overlap with any other network of an IP configured on the service.

As an example for 169.254.17.100/30 link-local network:

• Possible values for {tunnel_internal_ip} are "169.254.17.101" and "169.254.17.102".
• Whichever is configured would consider the another as the peer (which for instance the pinger, if enabled, would ping).
• Using either of the addresses mentioned above in any of the other tunnels under the same service as {tunnel_internal_ip} would not be possible because they reside inside the same network.

If the service {automatic_tunnel_internal_ip_allocation} is true the {tunnel_internal_ip} is automatically allocated and can't be explicitly assigned.

{internal_peer_ping_interval} must have a value of 0 (disabled) or an integer greater or equal to 5. When it is non-zero and {tunnel_internal_ip} is not "", ICMP echo requests ("pings") from this address at this interval are sent to the peer IP in the /30 network. This is useful primarily for enhanced tunnel liveness and failure detection.

IPSec authentication

Tunnel IPSec authentication object.

Attributes

Attribute	Accepted value	Required	Description
authentication	psk	yes	Authentication type. Only type static routes are supported currently.
psk	The PSK must be 8-64 characters in length. It cannot start with number zero (0). Alphanumeric characters, underscores (_) and periods (.) are allowed. Regexp pattern to validate is ^[a-zA-Z1-9_.][a-zA-Z0-9_.]+$.	no	The pre-shared key (PSK) value. Required when creating, can be omitted when modifying existing tunnel. The PSK value can not be viewed after creation, replace with new value to change it.
