[mythtv-users] IP Tunnel??

Thanks for your help but you have my senario right but the reason to move wrong.
I am moving the Backend because where it is at the minute I have to use "rabit ears" antenna to pick up a tv signal. This is a very poor signal so I have proposed to move my backend and place it in a room where I have direct acess to a external antenna thus creating a strong signal. Then I hope to talk to the frontend from here?? Any ideas of how i would set up such a system??

Let's see if we understand the question:

1. You have a subnetwork (like a 192.168.x.x) behind an access point that runs network address translation (NAT), say in your dorm room?

2. You want to move the backend to a network outside your local NAT onto the main campus network (friends with root are friends indeed :-) to get better bandwidth to the internet?

The answer is most likely yes, but should you?  Right now your front end and backend are talking to each other over a local network switch.  When you watch TV, the stream between front-end and back-end might average 3Mb/sec (depending on transcoder settings).  My guess is that your busy college network will give you really poor performance if you are competing with multiple users on the college network.  

If you don't have to move the backend box to change networks, why not just plug your NAT device into the campus network?  Alternatively, beg borrow or buy a PCI network interface card (they are probably $10 on newegg.com and are often found as trash in computer lab equipment rooms) and install a second card into your backend.  One card is the local lan, the new card connects to the campus network.  Best of both worlds.

I have setup a subnetwork inside a college network in which i currently have a backend and frontend mythbox. I wish to move my backend out of this subnetwork and onto the main network in order to get a better signal? Is it possible that I could do this and leave the frontend where it is and setup and IP tunnel through the network and if so how would I go about it??
