reach the Internet thanks to NAT translation described in SOHO #004
reach now their favorite Internet service by name thanks for SOHO #005
and get IPv4 (or IPv6) address from DHCP server (we took as a switch connected to sdn6)
this applies to all wired host but also all mobile host connected to the home wireless network

Requirement

Basic Linux/Unix knowledge

Overview

I'm very fond listening music at home and started my personal music collection. I was aware of this practice, and since then started 24/96 flac collection. As mechanical hard drives became more and more affordable, storage was not an issue for the NAS I deployed. I purchased then a refurbished but still decent DLNA network player (DMP) that would be able to stream music sources from DLNA server(DMS). All of this is orchestrated though my mobile phone acting as DLNA media controller (DMC). So far so good, but DLNA alliance expects that all DLNA protagonists are in the same and unique broadcast domain.

In this article we will pursue the SOHO network appliance installation and enable THE UNIQUE freeRouter feature that you won't find in any router in the world: UPNP forwarder server.

title	Step -2- Configure UPNP forwarder client

Now that you have an UPNP hub, we need to configure any upnp forwarder client where we expect to see any incoming UPNP/DLNA message

Code Block

language	bash
theme	Midnight
title	UPNP forwarder client @ integrated WIFI

server upnpfwd wifi4-appliance
 target 192.168.254.1
 interface hairpin12
 vrf inet
 exit

In this case, WIFI network we encompasses all mobile clients. My phone is acting as DMC here, but it could also be a DMS. The upnp forwarder:

has a target UPNP hub (we configured 102.168.254.1)
is bound to interface sdn2
operates within VRF inet

Code Block

language	bash
theme	Midnight
title	UPNP forwarder client @ integrated WIFI

server upnpfwd wired-media
 target 192.168.254.1
 interface sdn2
 vrf inet
 exit

In this precise case wired-media is another UPNP fowarder client that will forward all UPNP message to UPNP hub 192.168.254.1. As you might have guessed behind sdn2 is cascaded my NAS and DLNA network streamer (DMP or DMR)

Tip

title	Tip

In this example the key idea is:

Create a UPNP hub
Create a UPNP forwarder bound to any interface where you expect DLNA/UPNP communication
In this case DMS and DMR are behind sdn2
DMC is behind WIFI
