Servicio Back to My Mac y router HGW-2501GN-R2

[mcdado]

perdon el ingles, no hablo español muy bien…

I want to enable NAT-PMP / UPnP on the HGW-2501GN-R2 router, to use Screens Connect on my Mac, and also the built-in Back To My Mac.

I entered the router advanced configuration, and in the LAN settings I went to UPnP and enabled it. I also tried restarting the router but any app using NAT-PMP won't connect.

Am I missing something or this router is somehow faulty?

uPnP work pretty fine on HGW, the problem is related on how Apple use mDNS to device's discovered in the network. Apple's upnp implementation is, at best, very poor, they dont like upnp, only mdns (bonjour).

In others hands, mdns will never work well on Movistar's Routers, because TV use multicast traffic for streaming, so IGMP Snooping is mandatory. mdns use multicast device<->device traffic, so in the end, you will have troubles.

You can find the same behavior in most of network devices with Apple (other Routers, APs, Switchs...). I am afraid that the culprit of this is Apple, and I doubt very much that it renounces to use mdns

Thanks, very informative. 

Indeed even they tried to move off mdns with discoveryd, but had to rollback.

Well, I don't know if it would have made a difference.

But then is it normal that other apps on the system cannot use UPnP or is it just about Back To My Mac?

Es un problema de los Apple y su implementación del UPnP, no de la app Back to my MAC. Si usas una consola de videojuegos verás que el UPnP funciona correctamente.
