MVP via internet

[JytteM]

is it at all possible?

I have a server in one location, internet 2Mb.sdsl and a mvp at home 512/2048 adsl

I don't want anyone to connect, but in the firewalls I can open a point-to-point connection, just have no idea what ports to open in either direction?

the ISP at home has closed 137-139 else nothing.

No, its not possible. The MVP uses UDP broadcasts to boot and locate its MVP server. These dont travel across the internet.

This is a stretch, but has the potenial to work. Get a VPN router for home use. Configure the server at work to establish a VPN tunnel to the router, which should give the server a network interface with an IP address on the home network. The server will appear to be on the home network. This will likely cause problems with your server, so is not recommended unless the server is specifically for your PVR needs. Not all Internet protocol are supported by various VPN solutions, so you would need to ensure that the router and VPN client on the server support the required protocols. The VPN will eat into your bandwidth, more so with more secure encryption. I am not sure that you will have enough bandwidth for the solution to work very well.

You would be better served to record at work and move the recordings to a server at home. If you use GBPVR on both ends, you might be able to export the recording on one end and import on the other. There is also an mpg import utility, but I am not sure it will work with the newest GBPVR software. My needs are simple, so I would just dump the recordings in a folder where the video library can access them.

ok, I see the implications, as the MVP needs to boot. However, the last version where it boots from one server but may connect to another, there mig be a possibility to do something like forward the udppackets from the mvp to the server(I can do so in my firewalls)? I take the server will answer the IP from where udppacket arrives, and then I can redirect those packets to my homefirewall. I then need the portnumbers.
I do believe the vpn might do, but it seemed to me as overkill. I might be wrong :-)

As Sub said, the issue is a matter of broadcast packets. Your router will not forward the broadcast packets during the discovery phase. The MVP would never see the remote server. This is probably true even if you get it to boot via a local server.

For this to work, you would need to create a proxy application that would forward the packets to the remote subnet. Or, as I suggested, get a local IP address from the remote subnet. I can't see a way to get the MVP to create the tunnel, so that leaves the server.

ok I bow and thanks :-)

Try this free software based VPN:
http://openvpn.net/
If you have a machine (L) on the same local network as the MVP, and use L as a bridge to the remote network ®, I believe it can be done. I am pretty sure OpenVPN supports a bridge mode, where all packets are transfered across the link. In short, you need OpenVPN running on a machine on your remote network R, and on a machine on your local network (L), L configured in bridge-mode.

Interesting. Would this bridge also rewrite the broadcast packets to propagate across the remote subnet? Bridges do not typically forward broadcast traffic.
