any ideas?

Go to Configuration -> DVB Inputs -> Networks.
Select the Network you're using for the tuner click Edit from the menu and where it says "SAT>IP Source Number:" enter the number you used in Exported Tuners.

It should work then.

I'm trying to do the same thing. I have one server where I export one DVT-T tuner and the client looks like:

The next tab looks like:

The Teracom_sat_ip network is assigned as a DVB-T network with sat>ip source number 1

Now I can't set "Network type". If I select DVB-T and "save" it will not be saved !? What is the UDP RTP port number ? If I try to add an MUX I get the following error:

2015-09-28 23:09:59.000 mpegts: 570MHz in Teracom_sat_ip - tuning on SAT>IP DVB-T Tuner #1 (192.168.0.93:9983)

It seems that I'm missing something. Do I need to add any network at the server side ? Shouldn't just the "server" adapter appears like an virtual adapter at the client side ?
