How do Dish Anywhere sessions work?
I am upgrading to a VIP722k and have connected it to the internet through a high speed 5Ghz 802.11n dedicated WiFi connection then then passes through a DSL router.
I am mostly curious on how Dish Anywhere actually works and what, if any, special configuration I need to set in my router.
I understand that the DVR connects to the Dish server and that when I log into dishanywhere.com, I am connecting to the Dish server which controls the whole process.
If I want to set the DVR to record a show, I assume that the server sends instructions to the DVR.
If I want to view live content or recorded content, I have read that the Dish Anywhere will utilize one of the tuners in the VIP722k. I do not know if that content comes directly from DVR or if it is transferred through the Dish server, but it seems logical that it would come directly from the DVR
What I do not get is how the Dish server communicates with the DVR or how a session is set up to connect the DVR and the DishAnywhere device (in my case a laptop). Unless it requires that the DVR initiate a session, it would seem to me that it would be necessary to set up some type of port forwarding to get any request from the server through a router and to the DVR. I guess this could be done through UPnP. (Although I prefer to turn off UPnP.)
If the Dish server needs to initiate a session, can port forwarding be specified, or does the system require UPnP? (I can find no way to set a static IP address or port for the VIP722k).
So, can anyone tell me how the sessions are initiated and maintained?

I am now thinking that all sessions must be initiated by the DVR.
The VIP722k shows up on my network as "new-host1". I can ping it and I can do a port scan on it. Apparently the only three ports that are open are 21 (FTP), 25 (SMTP), and 110(POP3).
Any attempt to attach to the DVR via FTP causes an immediate loss of connection - before any possible authentication. So I am thinking that the DVR is programmed to never accept any incoming FTP connection. If all internet sessions are initiated by the DVR, then there is no for port forwarding.
Do you have the sling adapter? Dish Anywhere requires that a sling adapter be connected to the 722.
Sling Box would be another option.
The Dish server just initiates the session. Your program does not go thru to Dish then to you.
Almost nobody has to change their router. You're making this out to be a lot harder than it is.

Thanks NavyChop. I do not have a sling box, and, yes, it seems as if all I need to do is connect the DVR to a good Ethernet network and forget it.
The reason for my thread was to understand how it does it - manages and controls communication among the Dish Anywhere app or program, the Dish server, and the DVR...
Why? Just because I kind of like to know the technology I am using. ;-)
I have had my 722 for some time now, I recently got a smart phone and the sling adaptor and then I downloaded the app to the phone. I was able to view off tuner 2 and existing dvr recordings without much trouble and I never changed anything on my server or router. Just remember the 722 needs to be connected to your broadband.
