The Anatomy of UPnP Device Discovery

Since my Cisco ICND1 training last week, I’ve become somewhat obsessed. I’ve previously been looking at NETGEAR routers to replace my current FVG318 as I am hitting the concurrent connection limit on it almost daily. Due to now seeing a little piece of Cisco, I figured why not look at getting a Cisco router so that the router will be more reliable and also will help give me some on the job training.

Everything was looking good until I thought about UPnP. I use UPnP quite heavily at home: Not for the port forwarding but for the internal advertisement of network services (namely media streaming to the PlayStation 3).

I discovered a few articles which outlined that Cisco doesn’t support UPnP on any of its devices and that it looks like there is no plan to add support for it either which is a bad thing if you are an SME looking for easy to deploy networking products but good from a security standpoint I suppose.

To test, on the FVG318, I disabled UPnP and had Nicky test the media streaming, however it didn’t work so today I took it upon myself to test this to ensure I can actually achieve full functionality using a Cisco 2651XM.

More Lies: Revenge of the Stupid

So after the post titled Why Do People Lie, I continued to phone Virgin to chase them and on my final call of the day I got put through to the installation manager for our area, although he was actually quite possibly the tea boy in the office.
