The Transparent proxy model allows the Border Router to forward traffic on behalf of Wi-SUN nodes so that they appear as directly attached hosts on the upstream network, even though there is a routing hop between the upstream and the Wi-SUN devices.

To use this option, the Networking mode must be set to "Transparent proxy".

> config network interface wisun networking_mode transparent_proxy

In the Web UI, go to System → Configuration → Device Configuration, then navigate to Network → Interfaces → Wi-SUN → Networking mode and set the value to Use IPv6 transparent proxy.

dal webui config network interfaces wisun

Configuration

You can configure the Transparent proxy parameters:

> config network interface wisun transparent_proxy

In the Web UI, go to System → Configuration → Device Configuration, then navigate to Network → Interfaces → Wi-SUN → Transparent Proxy.

dal webui config network interfaces wisun transparent proxy
The Transparent Proxy needs to be enabled as done above for the fields to be visible.
Field Default Value Description

interface

'ETH1'

The upstream interface used to bridge all Wi-SUN network traffic. Forwards DHCPv6 relay messages. Typically an Ethernet or WAN interface.

prefix

'required_value'

The IPv6 prefix of the Proxy interface name selected above. This prefix will be used when assigning IPv6 addresses to the Wi-SUN nodes. (e.g. 2001:db8::/32)

See IPv6 addressing for more information about prefix values.
Transparent Proxy works in tandem with Use DHCPv6 Relay.
