## Member Data Documentation

## ◆ networkName

attribute wstring INATNetwork::networkName

TBD: the idea, technically we can start any number of the NAT networks, but we should expect that at some point we will get collisions because of port-forwanding rules.

so perhaps we should support only single instance of NAT network.

## ◆ enabled

attribute boolean INATNetwork::enabled

## ◆ network

attribute wstring INATNetwork::network

This is CIDR IPv4 string.

Specifying it user defines IPv4 addresses of gateway (low address + 1) and DHCP server (= low address + 2). Note: If there are defined IPv4 port-forward rules update of network will be ignored (because new assignment could break existing rules).

## ◆ gateway

readonly attribute wstring INATNetwork::gateway

This attribute is read-only.

It's recalculated on changing network attribute (low address of network + 1).

## ◆ IPv6Enabled

attribute boolean INATNetwork::IPv6Enabled

This attribute define whether gateway will support IPv6 or not.

## ◆ IPv6Prefix

attribute wstring INATNetwork::IPv6Prefix

This a CIDR IPv6 defining prefix for link-local addresses autoconfiguration within network.

Note: ignored if attribute IPv6Enabled is false.

## ◆ advertiseDefaultIPv6RouteEnabled

attribute boolean INATNetwork::advertiseDefaultIPv6RouteEnabled

## ◆ needDhcpServer

attribute boolean INATNetwork::needDhcpServer

## ◆ eventSource

readonly attribute IEventSource INATNetwork::eventSource

## ◆ portForwardRules4

readonly attribute wstring [] INATNetwork::portForwardRules4

Array of NAT port-forwarding rules in string representation, in the following format: "name:protocolid:[host ip]:host port:[guest ip]:guest port".

## ◆ localMappings

readonly attribute wstring [] INATNetwork::localMappings

Array of mappings (address,offset),e.g.

("127.0.1.1=4") maps 127.0.1.1 to networkid + 4.

## ◆ loopbackIp6

attribute long INATNetwork::loopbackIp6

Offset in ipv6 network from network id for address mapped into loopback6 interface of the host.

## ◆ portForwardRules6

readonly attribute wstring [] INATNetwork::portForwardRules6

Array of NAT port-forwarding rules in string representation, in the following format: "name:protocolid:[host ip]:host port:[guest ip]:guest port".
